[OpenFCoE] [PATCH] (user-libfc) Change the default FCoE protocol version to the T11 (Aug. 2007) version.

[Joe Eykholt <fcoe@eykholt.com>]

Change the default FCoE protocol version to the T11 (Aug. 2007) version.

Use environment to override:  export FCOE_OLD_ALL=1 to use the old protocol
on all interfaces, or FCOE_OLD_eth0=1 to use it on eth0.
