[Intel-wired-lan] [PATCH] ixgbe: fix documentation

From: Stephen Hemminger <stephen at networkplumber.org>
The MTU values in the documentation do not match the source.
The source has frame limit of IXGBE_MAX_JUMBO_FRAME_SIZE (9728)
which is MTU of 9710 because of the accounting for Ethernet header
and CRC.
Also, don't refer to the obsolete ifconfig command.
