[PATCH 05/14] MIPS: OCTEON: configure minimum PKO packet sizes on CN68XX

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Janne Huttunen <janne.huttunen@xxxxxxxxx>

CN68XX has common minimum packet size filters that need to be configured
for the traffic to work. Just set them to a default value.
