New 7.0 FW: bnx2x, cnic, bnx2i, bnx2fc
New FW/HSI (7.0):
- Added support to 578xx chips
- Improved HSI - much less driver's direct access to the FW internal
memory needed.
New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c):
- Introduced chip dependent objects that have chip independent interfaces
for configuration of MACs, multicast addresses, Rx mode, indirection table,
fast path queues and function initialization/cleanup.
- Objects functionality is based on the private function pointers, which
allows not only a per-chip but also PF/VF differentiation while still
preserving the same interface towards the driver.
- Objects interface is not influenced by the HSI changes which do not require
providing new parameters keeping the code outside the bnx2x_sp.c invariant
with regard to such HSI chnages.
Changes in a CNIC, bnx2fc and bnx2i modules due to the new HSI.
