From: Krishna Gudipati <kgudipat@xxxxxxxxxxx>
Change details:
- Introduced partitioning of the BFA resources.
- Added h/w queue ID in CPE messages, firmware uses h/w queue ID
from messages to pick a matching RME queue.
- Added message header to bfa_reqq_produce(). h/w queue ID is set
in the message header and firmware modules use h/w queue ID from
message header instead of from cpqe event.
- Made changes to allow using all 256 queues of Brocade-1860 asic.
Previously only a single queue per queue group was used.
- Added function tag to BFI message header. Only used by FC BFI messages.
Used to translate host tag to firmware tag. bfa_lpuid() is changed to
bfa_fn_lpu() that encodes both PCI function and port ID in BFI message header.
