It seems that trivial reset of pcount to one was not sufficient in tcp_retransmit_skb. Multiple counters experience a positive miscount when skb's pcount gets lowered without the necessary adjustments (depending on skb's sacked bits which exactly), at worst a packets_out miscount can crash at RTO if the write queue is empty! Triggering this requires mss change, so bidir tcp or mtu probe or like. Signed-off-by:

We need full-scale adjustment to fix a TCP miscount in the next patch, so just move it into a helper and call for that from the other places. Signed-off-by:

Some devices cannot send very short usb transfers. To get around this the firmware adds a known pattern and flags the driver that it should check for this pattern on short transfers. This flag was not taken into account by the driver. Signed-off-by:

commit 1577ecef ("netdev: Merge UCC and gianfar MDIO bus drivers") introduced a regression so that UCC MDIO buses no longer work. This is because fsl_pq_mdio driver wrongly masks all non-TBI PHYs for !fsl,gianfar-mdio buses, while it should do that only for fsl,gianfar-tbi buses. Signed-off-by:

The driver should pass a device that actually specifies internal DMA ops, but currently it passes netdev's device, which is wrong and that causes following oops: Kernel BUG at c01c4df8 [verbose debug info unavailable] Oops: Exception in kernel mode, sig: 5 [#1] [...] NIP [c01c4df8] get_new_skb+0x7c/0xf8 LR [c01c4da4] get_new_skb+0x28/0xf8 Call Trace: [ef82be00] [c01c4da4] get_new_skb+0x28/0xf8 (unreliable) [ef82be20] [c01c4eb8] rx_bd_buffer_set+0x44/0x98 [ef82be40] [c01c62bc] ucc_geth_startup+0x11b0/0x147c [ef82be80] [c01c6674] ucc_geth_open+0xec/0x2a4 [ef82bea0] [c02288a4] dev_open+0xc0/0x11c [...] Fix this by passing of_device's device that specifies DMA ops in its archdata.

GRO assumes that there is a one-to-one relationship between NAPI structure and network device. Some devices like sky2 share multiple devices on a single interrupt so only have one NAPI handler. Rather than split GRO from NAPI, just have GRO assume if device changes that it is a different flow. Signed-off-by:

Original comment (Karsten): On a MSI MS-6702E mainboard, when in rtl8169_init_one() for the first time after BIOS has run, IntrStatus reads 5 after chip has been reset. IntrStatus should equal 0 there, so patch changes IntrStatus reset to happen after chip reset instead of before. Remark (Francois): Assuming that the loglevel of the driver is increased above NETIF_MSG_INTR, the bug reveals itself with a typical "interrupt 0025 in poll" message at startup. In retrospect, the message should had been read as an hint of an unexpected hardware state several months ago :o( Fixes (at least part of) https://bugzilla.redhat.com/show_bug.cgi?id=460747Signed-off-by:

In the past flow control wasn't enabled by default under the incorrect assumption that this opened up us to a denial of service attack. However since any switch that forwarded flow control would be extremely msiconfigured and/or buggy, this concern no longer out weighs the preformance gains from having FC enabled. Signed-off-by:

Impact: Fix Yinghai Lu found one system with 82575EB where, in the kernel that is kexeced, probe igb failed with -2, the reason being that the adapter could not be brought back from D3 by the kexec kernel, most probably due to quirky hardware (it looks like the same behavior happened on forcedeth). Prevent igb from putting the adapter into D3 during shutdown except when we going to power off the system. For this purpose, seperate igb_shutdown() from igb_suspend() and use the appropriate PCI PM callbacks in both of them. Signed-off-by:

We have a 64bit value that needs to be set atomically. This is easy and quick on all 64bit archs, and can also be done on x86/32 with set_64bit() (uses cmpxchg8b). However other 32b archs don't have this. I actually changed this to the current state in preparation for mainline because the old way (using a spinlock on 32b) resulted in unsightly #ifdefs in the code. But obviously, being correct takes precedence. Signed-off-by:
