           ^^^^^^^^^^^^^^^^^^^^^^^^^^
According to IEEE stanards OUI database the manufacturer is Atheros
Communications. Since Atheros acquired Attansic Technology I guess
the phy originated from Attansic Technology. ATM there is no phy
driver for FreeBSD and the vendor didn't release publicly available
datasheets to developers. AFAIK kevlo is working on Attansic driver
so I guess he may have more information for this phy hardware(CCed).

Don't worry about that. Your nfe(4) takes advantage of MSI so there
is no IRQ sharing.
