The 57840 boards come in two flavours: 2 x 20G and 4 x 10G. To better differentiate between the two flavours, a separate device ID was assigned to each. The silicon default value is still the currently supported 57840 device ID (0x168d), and since a user can damage the nvram (e.g., 'ethtool -E') the driver will still support this device ID to allow the user to amend the nvram back into a supported configuration.

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.

2012-07-08net: dont use __netdev_alloc_skb for bounce bufferEric Dumazet
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.

2012-06-27cnic: Fix occasional NULL pointer dereference during reboot.Michael Chan
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.

2012-06-19bnx2x: Make the transmission queues adjacentMerav Sicron
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>
