2009-09-03enic: workaround A0 erratumScott Feldman
A0 revision ASIC has an erratum on the RQ desc cache on chip where the cache can become corrupted causing pkt buf writes to wrong locations. The s/w workaround is to post a dummy RQ desc in the ring every 32 descs, causing a flush of the cache. A0 parts are not production, but there are enough of these parts in the wild in test setups to warrant including workaround. A1 revision ASIC parts fix erratum.

2009-09-03macvlan: add multiqueue capabilityEric Dumazet
macvlan devices are currently not multi-queue capable. We can do that defining rtnl_link_ops method, get_tx_queues(), called from rtnl_create_link() This new method gets num_tx_queues/real_num_tx_queues from lower device. macvlan_get_tx_queues() is a copy of vlan_get_tx_queues(). Because macvlan_start_xmit() has to update netdev_queue stats only (and not dev->stats), I chose to change tx_errors/tx_aborted_errors accounting to tx_dropped, since netdev_queue structure doesnt define tx_errors / tx_aborted_errors.

The FCoE DDP in 82599 can be used for both FCoE initiator as well as FCoE target, depending on the indication of the exchange being the responder or originator in the F_CTL (frame control) field in the encapsulated Fiber Channel frame header (T10 Spec., FC-FS). For the initiator, OX_ID is used for FCoE DDP, where for the target RX_ID is used for FCoE DDP.

2009-09-03ixgbe: Add support for multiple Tx queues for FCoE in 82599Yi Zou
This patch adds support for multiple transmit queues to the Fiber Channel over Ethernet (FCoE) feature found in 82599. Currently, FCoE has multiple Rx queues available, along with a redirection table, that helps distribute the I/O load across multiple CPUs based on the FC exchange ID. To make this the most effective, we need to provide the same layout of transmit queues to match receive. Particularly, when Data Center Bridging (DCB) is enabled, the designated traffic class for FCoE can have dedicated queues for just FCoE traffic, while not affecting any other type of traffic flow.

2009-09-02NET: Fix possible corruption in bpqether driverRalf Baechle
The bpq ether driver is modifying the data art of the skb by first dropping the KISS byte (a command byte for the radio) then prepending the length + 4 of the remaining AX.25 packet to be transmitted as a little endian 16-bit number. If the high byte of the length has a different value than the dropped KISS byte users of clones of the skb may observe this as corruption. This was observed with by running listen(8) -a which uses a packet socket which clones transmit packets. The corruption will then typically be displayed for as a KISS "TX Delay" command for AX.25 packets in the range of 252..508 bytes or any other KISS command for yet larger packets. Fixed by using skb_cow to create a private copy should the skb be cloned. Using skb_cow also allows us to cleanup the old logic to ensure sufficient headroom in the skb. While at it, replace a return of 0 from bpq_xmit with the proper constant NETDEV_TX_OK which is now being used everywhere else in this function. Affected: all 2.2, 2.4 and 2.6 kernels.
