There are few issues with the RPM driver, such as FIFO overflow 
and network performance problems due to wrong FIFO values. This
patchset adds fixes for the same.


Patch1: Fixes the mismatch between the lmac type reported by the driver 
        and the actual hardware configuration.

Patch2: Addresses low network performance observed even on RPMs with 
        larger FIFO lengths.

Patch 3 & 4: Fix the stale FEC counters reported by the driver by 
             accessing the correct CSRs

Patch 5: Resolves the issue related to RPM FIFO overflow during system 
         reboots
