2012-11-09gianfar: ethernet vanishes after restoring from hibernationWang Dongsheng1-1/+4
If a gianfar ethernet device is down prior to hibernating a system, it will no longer be present upon system restore. For example: ~# ifconfig eth0 down ~# echo disk > /sys/power/state <trigger a restore from hibernation> ~# ifconfig eth0 up SIOCSIFFLAGS: No such device This happens because the restore function bails out early upon finding devices that were not up at hibernation. In doing so, it never gets to the netif_device_attach call at the end of the restore function. Adding the netif_device_attach as done here also makes the gfar_restore code consistent with what is done in the gfar_resume code.

2012-10-23pch_gbe: don't reset MAC_RX on FIFO overflowVeaceslav Falico1-60/+6
Currently, when FIFO_ERR happens, we stop the dma, wait for it to become idle and then reset the whole MAC_RX logic (and after that we must re-set multicast addresses and also re-enable MAC_RX when we're finally ready to accept new packets). This leads to CRC errors on high number of incoming packets and is not needed according to the datasheet. This patch fixes it by the following steps: 1) remove this reset in pch_gbe_stop_receive(), which causes some functions to not be used anywhere 2) remove already unused functions pch_gbe_wait_clr_bit_irq() and pch_gbe_mac_reset_rx() to correctly build 3) move pch_gbe_enable_mac_rx() out of pch_gbe_start_receive() to pch_gbe_up() where it's only needed after we've removed the MAC_RX reset 4) rename pch_gbe_start/stop_receive() to pch_gbe_enable/disable_dma_rx() to more precisely reflect what the functions are now doing. After these changes we already don't see the CRC errors and gain some increase in RX processing speed. Signed-off-by: Veaceslav Falico <vfalico@redhat.com> Signed-off-by: David S.

2012-10-10e1000e: Change wthresh to 1 to avoid possible Tx stallsHiroaki SHIMODA2-4/+4
This patch originated from Hiroaki SHIMODA but has been modified by Intel with some minor cleanups and additional commit log text. Denys Fedoryshchenko and others reported Tx stalls on e1000e with BQL enabled. Issue was root caused to hardware delays. They were introduced because some of the e1000e hardware with transmit writeback bursting enabled, waits until the driver does an explict flush OR there are WTHRESH descriptors to write back. Sometimes the delays in question were on the order of seconds, causing visible lag for ssh sessions and unacceptable tx completion latency, especially for BQL enabled kernels. To avoid possible Tx stalls, change WTHRESH back to 1. The current plan is to investigate a method for re-enabling WTHRESH while not harming BQL, but those patches will be later for net-next if they work. please enqueue for stable since v3.3 as this bug was introduced in commit 3f0cfa3bc11e7f00c9994e0f469cbc0e7da7b00c Author: Tom Herbert <therbert@google.com> Date: Mon Nov 28 16:33:16 2011 +0000 e1000e: Support for byte queue limits Changes to e1000e to use byte queue limits.

It's a regression by commit da1586461.

2012-10-09ixgbe/ixgbevf: Limit maximum jumbo frame size to 9.5K to avoid Tx hangsAlexander Duyck2-2/+2
This change limits the PF/VF driver to 9.5K max jumbo frame size in order prevent a possible Tx hang in the adapter when sending frames between pools. All of the parts in ixgbe support a maximum frame of 15.5K for standard traffic, however with SR-IOV or DCB enabled they should be limiting the MTU size to 9.5K. Instead of adding extra checks which would have to change the MTU when we go into or out of these modes it is preferred to just use a standard 9.5K MTU limit for all modes so that this extra overhead can be avoided.

2012-10-09ixgbevf: Set the netdev number of Tx queuesGreg Rose1-0/+7
The driver was not setting the number of real Tx queues in the net_device structure. This caused some serious issues such as Tx hangs and extremely poor performance with some usages of the driver. The issue is best observed by running: iperf -c <host> -P <n> Where n is greater than one. The greater the value of n the more likely the problem is to show up.

2012-10-09Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linusLinus Torvalds2-134/+446
Pull MIPS update from Ralf Baechle: "This is the MIPS update for 3.7. A fair chunk of them are platform updates to the Cavium Octeon SOC (which involves machine generated header files of considerable size), Atheros ATH79xx, RMI aka Netlogic aka Broadcom XLP, Broadcom BCM63xx platforms. Support for the commercial MIPS simulator MIPSsim has been removed as MIPS Technologies is shifting away from this product and Qemu is offering various more powerful platforms. The generic MIPS code can now also probe for no-execute / write-only TLB features implemented without the full SmartMIPS extension as permitted by the latest MIPS processor architecture. Lots of small changes to generic code." * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (78 commits) MIPS: ath79: Fix CPU/DDR frequency calculation for SRIF PLLs MIPS: ath79: use correct fractional dividers for {CPU,DDR}_PLL on AR934x MIPS: BCM63XX: Properly handle mac address octet overflow MIPS: Kconfig: Avoid build errors by hiding USE_OF from the user.

2012-10-08net: gro: selective flush of packetsEric Dumazet2-2/+2
Current GRO can hold packets in gro_list for almost unlimited time, in case napi->poll() handler consumes its budget over and over. In this case, napi_complete()/napi_gro_flush() are not called. Another problem is that gro_list is flushed in non friendly way : We scan the list and complete packets in the reverse order. (youngest packets first, oldest packets last) This defeats priorities that sender could have cooked. Since GRO currently only store TCP packets, we dont really notice the bug because of retransmits, but this behavior can add unexpected latencies, particularly on mice flows clamped by elephant flows. This patch makes sure no packet can stay more than 1 ms in queue, and only in stress situations. It also complete packets in the right order to minimize latencies.

2012-10-08skge: Add DMA mask quirk for Marvell 88E8001 on ASUS P5NSLI motherboardGraham Gower1-0/+7
Marvell 88E8001 on an ASUS P5NSLI motherboard is unable to send/receive packets on a system with >4gb ram unless a 32bit DMA mask is used. This issue has been around for years and a fix was sent 3.5 years ago, but there was some debate as to whether it should instead be fixed as a PCI quirk. http://www.spinics.net/lists/netdev/msg88670.html However, 18 months later a similar workaround was introduced for another chipset exhibiting the same problem. http://www.spinics.net/lists/netdev/msg142287.html Signed-off-by: Graham Gower <graham.gower@gmail.com> Signed-off-by: Jan Ceuleers <jan.ceuleers@computer.org> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.
