Subject: i40e/base: add flag for X722 register access
X-Git-Tag: spdx-start~7385
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=dd59229c8bb4555727b75a2d373fcf026e8871de;p=dpdk.git

i40e/base: add flag for X722 register access

Instead of doing the MAC check, use a flag that gets set per
MAC. This way there are less chances of user error and it
can enable multiple MACs with the capability in a single place
rather than cluttering the code with MAC checks.
