Subject: [net-next patch] bnx2x,bnx2fc,bnx2i,cnic: Add statistics
support and FCoE capabilities advertisement
From: Barak Witkowski <barak@...adcom.com>
1. When FCoE offload driver is registered, copy its capabilities to the chip
scratchpad.
2. Copy FCoE/iSCSI MAC addresses in aligned manner to chip scratchpad.
3. Add FCoE/iSCSI statistics collection support
