2011-09-15stmmac: add HW DMA feature register (v3)Giuseppe CAVALLARO6-1/+174
New GMAC chips have an extra register to indicate the presence of the optional features/functions of the DMA core. This patch adds this support and all the HW cap are exported via debugfs.

2011-09-15stmmac: rework the code to get the Synopsys ID (v3)Giuseppe CAVALLARO4-5/+23
The Synopsys ID is now passed from the MAC core to the main. This info will be used for managing the HW cap register (supported in the new GMAC generations). Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-09-15stmmac: export DMA TX/RX rings via debugfs (v3)Giuseppe CAVALLARO2-0/+112
This patch adds the following debugFs entry to dump the RX/TX DMA rings: /sys/kernel/debug/stmmaceth/descriptors_status This is an example: ======================= RX descriptor ring ======================= [0] DES0=0x85ee0320 DES1=0x1fff1fff BUF1=0x5fae2022 BUF2=0x0 [1] DES0=0x85ee0320 DES1=0x1fff1fff BUF1=0x5fae0022 BUF2=0x0 [2] DES0=0x81460320 DES1=0x1fff1fff BUF1=0x5f9dd022 BUF2=0x0 Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.

2011-09-15stmmac: add MMC support exported via ethtool (v3)Giuseppe CAVALLARO8-22/+540
This patch adds the MMC management counters support. MMC module is an extension of the register address space and all the hardware counters can be accessed via ethtoo -S ethX. Note that, the MMC interrupts remain masked and the logic to handle this kind of interrupt will be added later (if actually useful).

2011-09-15stmmac: support wake up irq from external sources (v3)Deepak Sikri3-3/+16
On some platforms e.g. SPEAr the wake up irq differs from the GMAC interrupt source. With this patch an external wake up irq can be passed through the platform code and named as "eth_wake_irq". In case the wake up interrupt is not passed from the platform so the driver will continue to use the mac irq (ndev->irq) Signed-off-by: Deepak Sikri <deepak.sikri@st.com> Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-09-15stmmac: remove the mmc code (v3)Giuseppe CAVALLARO4-28/+0
DWMAC Management Counters (MMC) are not fully support. The minimal support added in the past allowed to only disable counters (if present) and mask their interrupts. This patch prepares the driver to support the MMC removing obsolete code. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-09-15stmmac: remove the STBus bridge setting from the GMAC code (v3)Giuseppe CAVALLARO1-3/+0
This patch removes a piece of code (actually commented) only useful for some ST platforms in the past. This kind of setting now can be done by using the platform callbacks provided in linux/stmmac.h (see the stmmac.txt for further details).

2011-09-15net: linkwatch: allow vlans to get carrier changes fasterEric Dumazet1-2/+7
There is a time-lag of IFF_RUNNING flag consistency between vlan and real devices when the real devices are in problem such as link or cable broken. This leads to a degradation of Availability such as a delay of failover in HA systems using vlan since the detection of the problem at real device is delayed. We can avoid the linkwatch delay (~1 sec) for devices linked to another ones, since delay is already done for the realdev.

Change details: - Check the BNAD_RF_MBOX_IRQ_DISABLED flag after acquiring the bna_lock, since checking the flag and executing bna_mbox_handler needs to be atomic. If not, it opens up window where flag is reset when it was checked, but got set while spinning on the lock by the other thread which is actually holding the lock Signed-off-by: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

Get rid of Tx/Rx initialization from task q context - In the attach function, wait for IOC enable, then do Tx/Rx queue initialization. Default BNA attributes are used when IOC enable from attach fails and values are set to: 1 TxQ, 1 RxQ, 1 Unicast MAC, 1 RIT entry Signed-off-by: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

Change details: - Add tx_skb counters and NAPI debug counters to ethtool stats. - Add rlb stats strings to bnad_net_stats_strings{} array. rlb_stats field was added to struct bfi_enet_stats {} but the corresponding name structure array for ethtool was not initialized with right strings, even though the actual name structure array got expanded. This caused a NULL pointer violation and a crash when doing ehtool -S <if_name>. - Modify dim timer stop logic to make it dependent on cfg and run flags - While setting the ring parameter restore the rx, vlan configuration and set rx mode - Indentation fix Signed-off-by: Gurunatha Karaje <gkaraje@brocade.com> Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

2011-09-15bna: TX Path and RX Path ChangesRasesh Mody2-95/+191
Change details: - Add bnad_pci_unmap_skb() API to unmap skb from transmit path and update the unmap index. Add more checks for illegal skbs in transmit path. Add tx_skb counters for dropped skbs. - The unmap_cons index used in bnad_free_txbufs() is incorrectly declared as u16. It quickly wraps around and accesses null sk_buff ptr. So using u32 to handle unmap_array. - Disable and enable interrupts from the same polling context to prevent reordering in Rx path. - Add Rx NAPI debug counters. - Make NAPI budget check more generic. - Modify dim timer stop logic to make it dependent on cfg and run flags - Handle reduced MSI-X vectors case in bnad_enable_msix. - Check for single frame TSO skbs and send them out as non-TSO. - Put memory barrier after bna_txq_prod_indx_doorbell().

2011-09-15bna: Interrupt Polling and NAPI Init ChangesRasesh Mody2-30/+54
Change details: - Remove unnecessary ccb check from bnad_poll_cq - Add bnad pointer to rx_ctrl structure, so that bnad can be accessed directly from rx_ctrl in the NAPI poll routines, even if ccb is NULL - Validate ccb before referencing to it in bnad_msix_rx and bnad_napi_poll_rx - Fix the order of NAPI init / uninit in Tx / Rx setup / teardown path: a. Kill bnad tx free tasklet ahead of call to bna_tx_destroy() b. Call NAPI disable only after call to Rx free_irq(). This makes sure Rx interrupt does not schedule a poll when NAPI is already disabled - NAPI poll runs before the h/w has completed configuration. This causes a crash. Delay enabling NAPI till after bna_rx_enable(). Split NAPI initialization into 2 steps, bnad_napi_init() & bnad_napi_enable().
