[PATCH] e100: Fix Tyan motherboard e100 not receiving IPMI commands

[Auke Kok]

From: David Graham <david.graham@intel.com>

The 82550 & 51 parts have an extended configuration block that
includes a bit "GMRC", required to enable the expected TCO behavior,
in config byte offset 22d.  The config block sent by the failing driver
does include the extension area, but this bit is not initialised,
and the downlaod only specifies 0x16 bytes to be sent to the NIC
(thaht's bytes 00..21d). By initializing the GMRC bit, and extending
the download size for D102+ MACs, the problem is resolved.
