Subject: net/sfc/base: guard Rx scale code with corresponding option
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=161c9ab395d5984967c33446f2d699c68bc9dd29;p=dpdk.git

net/sfc/base: guard Rx scale code with corresponding option

Previously only some of the code was guarded by this which caused
a build error when EFSYS_OPT_RX_SCALE is 0 (e.g. in manftest).
