[PATCH v2 net-next 0/4] bnx2x, cnic, bnx2fc: add support for BD

[PATCH v2 net-next 0/4] bnx2x, cnic, bnx2fc: add support for BD

[Yuval Mintz]

Commit 230d00eb4bfe ("bnx2x: new Multi-function mode - BD") added support
for a new multi-function mode, but it added only the support required by
bnx2x for L2 interfaces.

This adds the required changes to support the new multi-function mode in
the offloaded storage protocols.

Dave,

Please consider applying this series to `net-next'.

Do notice that this involves non-networking driver changes -
but sending this as a single series seemed like the best approach as
we had to have bnx2x changes to support the new functionality.
If this is problematic, please tell us what's the preferred solution here.

Changes from previous versions
------------------------------

 - From v1 - no actual changes; v1 failed to reach netdev so in order to
   keep things in line I've termed this one v2.

Thanks,
Yuval

[PATCH v2 net-next 3/4] bnx2x: Add BD support for storage

[Yuval Mintz]

Commit 230d00eb4bfe ("bnx2x: new Multi-function mode - BD") adds support
for the new mode in bnx2x. This expands this support by implementing
APIs required by our storage drivers to support that mode.
