    re(4): document jumbo frame support for 8168/8111 chips
    
    The man page only mentioned jumbo frame support for the 8169, 8169S,
    and 8110S chips. The 8168 and 8111 family also support jumbo frames,
    with varying MTU limits depending on the chip revision (6K for C
    variants, 9K for D and later). Update the documentation to reflect
    the actual driver capabilities.

-The MTU is limited to 7422, since the chip cannot transmit larger frames.
+The 8169, 8169S, 8110S, 8168 and 8111 also support jumbo frames,
+which can be configured via the interface MTU setting.
+The maximum MTU depends on the chip revision:
+the 8169, 8169S and 8110S support up to 7422 bytes;
+the 8168C/8111C and 8168E-VL/8111E-VL support up to approximately 6100 bytes;
+and the 8168D/8111D and later revisions support up to approximately 9200 bytes.
 Selecting an MTU larger than 1500 bytes with the
 .Xr ifconfig 8
 utility configures the adapter to receive and transmit jumbo frames.
