>Description:
I have a 64-bit PCI gigabit card, named SMC9462TX.
This card could be added to the list of known 64-bit devices in the 
gsip driver.

Dmesg shows:

>How-To-Repeat:

>Fix:
Add the entry
                /* SMC EZ Card */
                { 0x10b8,       0x9462 },
to the card64 array in sys/dev/pci/if_sip.c .

After recompile and reboot, the card is probed as

gsip0 at pci0 dev 6 function 0: NatSemi DP83820 Gigabit Ethernet, rev 00
gsip0: interrupting at eb164 irq 0
gsip0: Ethernet address 00:04:e2:10:51:aa
