[dpdk-dev] [PATCH v2 11/55] net/sfc: import libefx SFN8xxx family support
Andrew Rybchenko
arybchenko at solarflare.com
Tue Nov 29 17:18:43 CET 2016
SFN8xxx is the second family based on EF10 architecture.
It has few differences from SFN7xxx adapters family.
EFSYS_OPT_MEDFORD should be enabled to use it.
