Module Name: src
Committed By: mrg
Date: Wed Jul 31 23:47:16 UTC 2019
Modified Files:
src/sys/dev/usb: if_axen.c if_cdce.c usbnet.c usbnet.h
Log Message:
couple of minor API updates:
- change the read/write register callbacks to have the same phy/reg
order as the MII code.
- add "mii_flags" param to usbnet_attach_ifp(). axe(4) wants it.
also:
- add usbnet debug code, sysctl node support
- remove commented DPRINTF()s accidentally left in place
- add usbnet_softc()
- reorder some attach code to be consistent
- re-add USBD_FORCE_SHORT_XFER for axen rx chain
ride 9.99.2 bump.
