I am mistaken.  It was not working previously.  However I did find this post as
to a possible (?) fix;

https://forums.freebsd.org/threads/setting-up-ethernet-device-atheros-ar8161.60635/

Specifically;

 /*
        * Force maximum payload size to 128 bytes for
        * E2200/E2400/E2500.
        * Otherwise it triggers DMA write error.
        */
       if ((sc->alc_flags & ALC_FLAG_E2X00) != 0)
           sc->alc_dma_wr_burst = 0;
