--- Comment #4 from Jeff Pieper <jeffrey.e.pieper at intel.com> ---
This is not a bug. ixgbe devices do not support forcing speed using ifconfig,
only forced advertisement using sysctl. You need to use the advertise_speed
sysctl:

[root at test ~]# sysctl dev.ix.0.advertise_speed
dev.ix.0.advertise_speed: 6
[root at test ~]# sysctl -x dev.ix.0.advertise_speed
dev.ix.0.advertise_speed: 0x00000006
[root at test ~]# sysctl -d dev.ix.0.advertise_speed
dev.ix.0.advertise_speed: 
Control advertised link speed using these flags:
        0x1 - advertise 100M
        0x2 - advertise 1G
        0x4 - advertise 10G
        0x8 - advertise 10M

        100M and 10M are only supported on certain adapters.
