IB/mlx4: Add VLAN support for IBoE

2010-10-25T17:20:39+00:00

This patch allows IBoE traffic to be encapsulated in 802.1Q tagged
VLAN frames.  The VLAN tag is encoded in the GID and derived from it
by a simple computation.

The netdev notifier callback is modified to catch VLAN device
addition/removal and the port's GID table is updated to reflect the
change, so that for each netdevice there is an entry in the GID table.
When the port's GID table is exhausted, GID entries will not be added.
Only children of the main interfaces can add to the GID table; if a
VLAN interface is added on another VLAN interface (e.g. "vconfig add
eth2.6 8"), then that interfaces will not add an entry to the GID
table.

IB/mlx4: Add strong ordering to local inval and fast reg work requests

2009-06-05T17:36:24+00:00

The ConnectX Programmer's Reference Manual states that the "SO" bit
must be set when posting Fast Register and Local Invalidate send work
requests.  When this bit is set, the work request will be executed
only after all previous work requests on the send queue have been
executed.  (If the bit is not set, Fast Register and Local Invalidate
WQEs may begin execution too early, which violates the defined
semantics for these operations)

This fixes the issue with NFS/RDMA reported in

IB/mlx4: Add IPoIB checksum offload support

2008-04-17T04:01:10+00:00

ConnectX devices support checksum generation and verification of TCP
and UDP packets for UD IPoIB messages.  This patch checks if the HCA
supports this and sets the IB_DEVICE_UD_IP_CSUM capability flag if it
does.  It implements support for handling the IB_SEND_IP_CSUM send
flag and setting the csum_ok field in receive work completions.
