[dpdk-dev] [PATCH v3 10/10] net/bnx2x: merge debug register operations into headers

Chas Williams 3chas3 at gmail.com
Wed Oct 12 01:05:01 CEST 2016


The register read/writes should just be static inline instead of
alternately defined as routines or macros depending on the status of
debugging.

Fix bnx2x_reg_read32() returning 0 during debug unaligned reads.

Fixes: b5bf7719221d ("bnx2x: driver support routines")
