2012-07-17bnx2: Try to recover from PCI block resetMichael Chan1-0/+7
If the PCI block has reset, the memory enable bit will be reset and the device will not respond to MMIO access. bnx2_reset_task() currently will not recover when this happens. Add code to detect this condition and restore the PCI state. This scenario has been reported by some users. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S.

2012-07-17tg3: Fix the setting of the APE_HAS_NCSI flagMichael Chan1-21/+21
The driver currently skips setting this flag if the VPD contains the firmware version string. We fix this by separating the probing of NCSI from the reading of the NCSI version string. The APE_HAS_NCSI flag is needed to properly read sensor data. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

iterator variable If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. There does not seem to be a meaningful value to provide to netdev_warn. Replace with pr_warn, since pr_err is used elsewhere.

commit a1c7fff7e1 (net: netdev_alloc_skb() use build_skb()) broke b44 on some 64bit machines. It appears b44 and b43 use __netdev_alloc_skb() instead of alloc_skb() for their bounce buffers. There is no need to add an extra NET_SKB_PAD reservation for bounce buffers : - In TX path, NET_SKB_PAD is useless - In RX path in b44, we force a copy of incoming frames if GFP_DMA allocations were needed.

2012-06-28cnic: Fix occasional NULL pointer dereference during reboot.Michael Chan1-2/+7
We register with bnx2x before we allocate ctx_tbl structure, so it is possible for bnx2x to call cnic_ctl before the structure is allocated. This can sometimes cause NULL pointer dereference of cp->ctx_tbl. We fix this by adding simple checking for valid state before proceeding. The cnic_ctl call is RCU protected so we don't have to deal with race conditions. Because of the additional checking, we need to finish the shutdown before clearing the CNIC_UP flag.

Currently the CNIC-related L2 CIDs (for sending control FCoE / iSCSI packets) were at fixed position, according to the maximal number of RSS queues multiplied by the number of traffic-classes.

In the current scheme the transmission queues of traffic-class 0 were 0-15, the transmission queues of traffic-class 1 were 16-31 and so on. If the number of RSS queues was smaller than 16, there were gaps in transmission queues numbering, as well as in CIDs numbering. This is both a waste (especially when 16 is increased to 64), and may causes problems with flushing queues when reducing the number of RSS queues (using ethtool -L). The new scheme eliminates the gaps. Signed-off-by: Merav Sicron <meravs@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
