>Description:
share/man/man4/re.4 doesn't accurately reflect all the realtek nics which work with jumbo frames.

For example, my nic is:

re0 at pci0:3:0:0: class=0x020000 card=0x75811462 chip=0x816810ec rev=0x03 hdr=0x00
    vendor     = 'Realtek Semiconductor'
    device     = 'Gigabit Ethernet NIC(NDIS 6.0) (RTL8168/8111/8111c)'
    class      = network
    subclass   = ethernet

Which works perfectly well with these settings:

re0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 6000
        options=3898<VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC>
        ether 00:24:21:e3:e7:50
        inet 192.168.25.10 netmask 0xffffff00 broadcast 192.168.25.255
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active

This wasn't always the case since when I first got this system jumbo frames and FreeBSD didn't work.

The missing functionality appears to have been added since then.
