Subject: bnx2x: use mask in test_registers() to avoid parity error
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8eb5a20ccc67d85d52ead88fb263eb28814ca2b4;p=openwrt%2Fstaging%2Fblogic.git

bnx2x: use mask in test_registers() to avoid parity error

Properly mask the value to be written to the register (according to the register size) during the self-test.
Otherwise immediate parity error would be generated.
