I think your issue is different from the PR. There are several AX88178 variants that use different PHY and each controller/PHY combination require different GPIO programming and PHY specific initialization. Hans committed that part to P4 but it's not in CURRENT yet. Your controller looks like AX88772A, a second generation of AX88172. It's known that there is AX88772B, another variant of AX88772A, which can offload TX/RX checksum computation from CPU. These controllers seem to require controller specific magic to power up PHY as well as new GPIO configuration. Unfortunately it looks hard to write patches without real hardware access and ASIX no more provide data sheet for these newer controllers. > sysctl -a|grep date > kern.osreldate: 801000 > _______________________________________________ freebsd-usb@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
