Gigabit ethernet doesn't work on AI?

Connected my BBAI to a gigabit switch and it connects at 100Mb. It works fine at 100Mb, but I was hoping to get gigabit speeds. Looking at dmesg gives this:

[ 13.959591] cpsw 48484000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx
[ 13.959758] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
[ 16.006545] cpsw 48484000.ethernet eth0: Link is Down
[ 16.059292] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready
[ 17.031645] cpsw 48484000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx
[ 17.031849] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

I have tried several gig switches, and I plugged a laptop into the same ethernet cablet and it connects at 1Gb no problem. Is there an issue with the PHY on the BBAI? I know on the BBB, there was a reset issue with the PHY that would cause it not to come up correctly. Does the PHY on the BBAI also have issues?
