tg3: Fix crc errors on jumbo frame receive

2013-02-14T18:49:07+00:00

[ Upstream commit daf3ec688e057f6060fb9bb0819feac7a8bbf45c ] TG3_PHY_AUXCTL_SMDSP_ENABLE/DISABLE macros do a blind write to the phy auxiliary control register and overwrite the EXT_PKT_LEN (bit 14) resulting in intermittent crc errors on jumbo frames with some link partners. Change the code to do a read/modify/write. Signed-off-by: Nithin Nayak Sujir Signed-off-by: Michael Chan Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

tg3: Avoid null pointer dereference in tg3_interrupt in netconsole mode

2013-02-14T18:49:07+00:00

[ Upstream commit 9c13cb8bb477a83b9a3c9e5a5478a4e21294a760 ] When netconsole is enabled, logging messages generated during tg3_open can result in a null pointer dereference for the uninitialized tg3 status block. Use the irq_sync flag to disable polling in the early stages. irq_sync is cleared when the driver is enabling interrupts after all initialization is completed.

commit 4a25417c20fac00b3afd58ce27408f964d19e708 upstream. fix bug where a register which was only meant to be read in 578xx/57712 devices causes a bogus error message to be logged when read from other devices.

bnx2x: fix rx checksum validation for IPv6

2012-10-12T20:38:40+00:00

[ Upstream commit e488921f44765e8ab6c48ca35e3f6b78df9819df ] Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance regression for IPv6. Rx checksum offload does not work. IPv6 packets are passed to the stack with CHECKSUM_NONE. The hardware obviously cannot perform IP checksum validation for IPv6, because there is no checksum in the IPv6 header. This should not prevent us from setting CHECKSUM_UNNECESSARY. Tested on BCM57711. Signed-off-by: Michal Schmidt Acked-by: Eric Dumazet Acked-by: Eilon Greenstein Signed-off-by: David S.

bnx2: Fix bug in bnx2_free_tx_skbs().

2012-08-09T15:31:41+00:00

[ Upstream commit c1f5163de417dab01fa9daaf09a74bbb19303f3c ] In rare cases, bnx2x_free_tx_skbs() can unmap the wrong DMA address when it gets to the last entry of the tx ring. We were not using the proper macro to skip the last entry when advancing the tx index. Reported-by: Zongyun Lai Reviewed-by: Jeffrey Huang Signed-off-by: Michael Chan Signed-off-by: David S.

tg3: add device id of Apple Thunderbolt Ethernet device

2012-08-09T15:31:38+00:00

commit 02eca3f5f5e458c3a5d7b772bc8042ee2a4ebedf upstream. The Apple Thunderbolt ethernet device is already listed in the driver, but not hooked up in the MODULE_DEVICE_TABLE(). This fixes that and allows it to work properly. Signed-off-by: Greg Kroah-Hartman Acked-by: Michael Chan Signed-off-by: David S. Miller

bnx2x: fix panic when TX ring is full

2012-07-16T16:03:48+00:00

[ Upstream commit bc14786a100cc6a81cd060e8031ec481241b418c ] There is a off by one error in the minimal number of BD in bnx2x_start_xmit() and bnx2x_tx_int() before stopping/resuming tx queue. A full size GSO packet, with data included in skb->head really needs (MAX_SKB_FRAGS + 4) BDs, because of bnx2x_tx_split() This error triggers if BQL is disabled and heavy TCP transmit traffic occurs. bnx2x_tx_split() definitely can be called, remove a wrong comment.
