Subject: netxen_nic: Print ULA information
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5e7856b31d2848195981880b7f7b8857bd89c967;p=openwrt%2Fstaging%2Fblogic.git

netxen_nic: Print ULA information

This patch reads CAMRAM(0x178) where FW writes a key for ULA and non-ULA
adapter and based on the key, driver logs the message.
