[PATCH 1/2] net/ngbe: fix WOL and NCSI capability error

[Zaiyu Wang]

When determining NIC's WOL and NCSI capability via sub-system ID,
flag matching must be exact, not inclusive. Misidentifying WOL/NCSI
capability will skip PHY configuration, causing link-up failure.

Fixes: 5f1ab0d529fc ("net/ngbe: add WOL and NCSI capability")
