Promisc mode fix

Poblem observed on HP NC550SFP NIC

$ dmesg
oce0: <Emulex CNA NIC function:///10.0.664.0///> mem=20
0xfbff0000-0xfbff3fff,0xfbfc0000-0xfbfdffff,0xfbfa0000-0xfbfbffff irq 32=20

$ pciconf =E2=80=93vl
oce0 at pci0:4:0:0:        class=3D0x020000 card=3D0x1747103c chip=3D0x0700=
19a2=20
rev=3D0x02 hdr=3D0x00
     vendor     =3D 'Emulex Corporation'
     device     =3D 'OneConnect 10Gb NIC'
     class      =3D network
     subclass   =3D ethernet

Putting interface to promisc mode either by tcpdump, or by ifconfig oce0
promisc actually has no effect: only unicast frames with destination MAC
matching NIC's and broadcast frames are visible.

Patch fixes problem. It was received from Emulex tech support in June, but
haven't made it to HEAD yet.
