Subject: bnxt_en: Allocate rx_cpu_rmap only if Accelerated RFS is enabled.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=45019a180358c3cf290c3f3dc953c44f978d5527;p=linux-beck.git

bnxt_en: Allocate rx_cpu_rmap only if Accelerated RFS is enabled.

Also, no need to check for bp->rx_nr_rings as it is always >= 1.  If the
allocation fails, it is not a fatal error and we can still proceed.
