2009-12-08ixgbe: Fix TX stats accountingEric Dumazet2-16/+5
Here is an updated version, because ixgbe_get_ethtool_stats() needs to call dev_get_stats() or "ethtool -S" wont give correct tx_bytes/tx_packets values. Several cpus can update netdev->stats.tx_bytes & netdev->stats.tx_packets in parallel. In this case, TX stats are under estimated and false sharing takes place. After a pktgen session sending exactly 200000000 packets : # ifconfig fiber0 | grep TX TX packets:198501982 errors:0 dropped:0 overruns:0 carrier:0 Multi queue devices should instead use txq->tx_bytes & txq->tx_packets in their xmit() method (appropriate txq lock already held by caller, no cache line miss), or use appropriate locking. After patch, same pktgen session gives : # ifconfig fiber0 | grep TX TX packets:200000000 errors:0 dropped:0 overruns:0 carrier:0 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2009-12-08e1000e: only perform ESB2 MDIC workaround on certain configurationsBruce Allan2-33/+69
A workaround added for all ESB2 devices (adds a delay for all MDIC accesses which resolves an issue with the MDIC ready bit being set prematurely) is applicable only to devices in which the MAC-PHY interconnect is not operating in a certain mode with in-band MDIO. Check the control register for the operating mode and enable the workaround accordingly.

2009-12-08e1000e: replace incorrect use of GG82563_REG macroBruce Allan2-3/+7
The GG82563_REG() macro should not be used to determine the offset provided to the e1000e_[read|write]_kmrn_reg() functions since the first argument to the macro is already implied and gets masked off anyway in the functions. The resultant register reads/writes with this patch are functionally the same as before.

2009-12-07ath9k: fix tx status reportingFelix Fietkau1-1/+1
This patch fixes a bug in ath9k's tx status check, which caused mac80211 to consider regularly transmitted unicast frames as un-acked. When checking the ts_status field for errors, it needs to be masked with ATH9K_TXERR_FILT, because this field also contains other fields like ATH9K_TX_ACKED. Without this patch, AP mode is pretty much unusable, as hostapd checks the ACK status for the frames that it injects. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.

2009-12-07mwl8k: increase firmware loading timeoutsLennert Buytenhek1-3/+2
The time between loading the helper image and starting to upload the main firmware image should be at least 5 ms or so. We were doing an msleep(1) before, and 1 ms appears to not be enough in almost all cases, but building with HZ=100 has always masked this so far. Bumping the msleep argument to 5 fixes firmware loading e.g. when HZ=1000. Some firmware images need more than 200ms to initialize. Bump the ready code timeout to 500ms to accommodate for this.

2009-12-07mwl8k: allow more time for transmit rings to drainLennert Buytenhek1-60/+67
Before issuing any firmware commands, we wait for the transmit rings to drain, to prevent control versus data path synchronization issues. In some cases, this can end up taking longer than the current hardcoded limit of 5 seconds, for example if the transmit rings are filled with packets for a host that has dropped off the air and we end up retransmitting every pending packet at the lowest rate a couple of times. This patch changes mwl8k_tx_wait_empty() to only bail out on timeout expiry if there was no change in the number of packets pending in the transmit rings during the waiting period. If at least one transmit ring entry was reclaimed while we were waiting, we are apparently still making progress, and we'll allow waiting for another timeout period.

2009-12-07mwl8k: allow more time for firmware commands to completeLennert Buytenhek1-2/+11

2009-12-07mwl8k: properly report rate on received 40MHz packetsLennert Buytenhek1-2/+8
On 8366, bit 6 in the rx descriptor rate field indicates whether the packet was received on a 20MHz or 40MHz channel, and is not part of the MCS index. Handle this properly, which then prevents hitting the WARN_ON and being dropped in ieee80211_rx(). Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

2009-12-07mwl8k: fix addr4 zeroing and payload overwrite on DMA header creationLennert Buytenhek1-14/+15
When inserting a DMA header into a packet for transmission, mwl8k_add_dma_header() would blindly zero the addr4 field, which is not a good idea if the packet being transmitted is actually a 4-address packet. Also, if the transmitted packet was a 4-address with QoS packet, the memmove() to do the needed header reshuffling would inadvertently overwrite the first two bytes of the packet payload with the QoS field. This fixes both of these issues. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-12-07mwl8k: prevent corruption of QoS field on receiveLennert Buytenhek1-15/+31
Packets exchanged between the mwl8k driver and the firmware always have a 4-address header without QoS field. For QoS packets, the QoS field is passed to/from the firmware via the tx/rx descriptors. We were handling this correctly on transmit, but not on receive -- if a QoS packet was received, we would leave garbage in the QoS field in the packet passed up to the stack, which is Bad(tm). Also, if the packet received on the air was a 4-address without QoS packet, we would forget to skb_pull the 2-byte DMA length prefix off. This patch adds an argument to the ->rxd_process() receive descriptor operation to retrieve the QoS field from the receive descriptor, and extends mwl8k_remove_dma_header() to insert this field back into the packet if the packet received is a QoS packet. It also fixes mwl8k_remove_dma_header() to strip off the length prefix in all cases. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-12-07mwl8k: fix UPDATE_STADB command struct legacy_rates array lengthLennert Buytenhek1-38/+13
There exist 12 802.11b/g rates, but mwl8k supports two additional (non-standard) rates, and includes those rates in rate bitmasks and in its internal rate table that hardware rate indices index. Commit "mwl8k: report rate and other information for received frames" added one of the nonstandard rates to the mwl8k_rates table to make the OFDM rates in the table line up with the rate indices that are reported in the receive descriptor (so that we can just simply copy the receive descriptor rate index into ieee80211_rx_status::rate_idx) and bumped MWL8K_IEEE_LEGACY_DATA_RATES from 12 to 13, but this screwed up the UPDATE_STADB command struct layout, as it also uses that define, for its legacy_rates array. To avoid having to convert rate indices and legacy rate bitmaps (e.g. ieee80211_bss_conf::basic_rates) between the 12-rate mac80211 format and the 14-rate mwl8k format, we'll report all 14 rates in our wiphy's band, but filter out the nonstandard ones e.g. in the case of the UPDATE_STADB command which only accepts 12 rates. In the commands that accept 14 rates (SET_AID, SET_RATE), replace the use of the MWL8K_RATE_INDEX_MAX_ARRAY define in the command struct by the constant 14, to make it clearer that these commands accept 14 rates.

2009-12-07mwl8k: fix MCS bitmap size in SET_RATE commandLennert Buytenhek1-4/+3
The MCS bitmaps in the SET_RATE command structure were of the wrong size, due to use of the wrong define for the array length. Just hardcode the lengths as 16, and do the same for the MCS bitmaps in other command structures. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

2009-12-07Revert "pata_sis: Implement MWDMA for the UDMA 133 capable chips"Jeff Garzik1-69/+22
This reverts commit f20941f334d8fdb6b598658979709b4e94cd034b. Sergei Shtylyov notes "You call min() on uncomparables [in mwdma_clip_to_pio()], i.e. mwdma_to_pio[] contains XFER_PIO_* and adev->pio_mode - XFER_PIO_0 yields you a mode number. Thus the second argument will always "win" as a minimal one" Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related to mwdma_clip_to_pio(). The function can return values between 0 and 4 which obviously won't work well for the new code below for values >2 (i.e. resulting in out-of-bounds array access for the common-case of dev->pio_mode == XFER_PIO_4)." Bartlomiej Zolnierkiewicz also notes the patch is incomplete, failing to update MWDMA mode masks. Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
