Revision 27e0c31c5f27c1d1a1d9d135c123069f60dcf97b authored by Finn Thain on 22 January 2020, 22:07:26 UTC, committed by David S. Miller on 23 January 2020, 20:24:37 UTC
There are several issues relating to command register usage during
chip initialization.
Firstly, the SONIC sometimes comes out of software reset with the
Start Timer bit set. This gets logged as,
macsonic macsonic eth0: sonic_init: status=24, i=101
Avoid this by giving the Stop Timer command earlier than later.
Secondly, the loop that waits for the Read RRA command to complete has
the break condition inverted. That's why the for loop iterates until
its termination condition. Call the helper for this instead.
Finally, give the Receiver Enable command after clearing interrupts,
not before, to avoid the possibility of losing an interrupt.
