The BCM5704 has a smaller memory buffer space than earlier NICs,
and the bge(4) driver up to 5.1-RELEASE failed to take this into
account. I checked in a fix for this to 5-CURRENT and 4-STABLE
yesterday. You can apply the following workaround on your 5.1-RELEASE
systems to fix this (same workaround will work on 4.8-RELEASE as well):
- Bring up /sys/dev/bge/if_bge.c in your favorite editor.
- Search for the following line of code:
CSR_WRITE_4(sc, BGE_BMAN_MBUFPOOL_LEN, 0x18000);
It should appear twice in the bge_blockinit() function.
- Change 0x18000 to 0x10000 in both places.
- Recompile your kernel and/or if_bge.ko module.
The fix I made to 4-STABLE and 5-CURRENT does basically the same
thing, but only applies the different value for the 5704 ASIC.
