Module Name: src
Committed By: mrg
Date: Wed Jul 31 09:13:17 UTC 2019
Modified Files:
src/distrib/sets/lists/modules: mi
src/sys/dev/usb: files.usb if_axen.c if_axenreg.h if_cdce.c
src/sys/modules: Makefile
Added Files:
src/sys/dev/usb: usbnet.c usbnet.h
src/sys/modules/usbnet: Makefile
Log Message:
introduce a library of common code / backends to share code between
USB ethernet drivers.
usbnet.h introduces a new set of APIs to provide common solutions
for these driver features:
- USB endpoint pipe handling
- rx and tx chain handling
- generic handlers or support for several struct ifnet callbacks
- MII bus locking
- interrupt handling
- partial autoconf handling: much of attach, and detach/activate
can use common versions directly.
currently, only axen(4) and cdce(4) are converted. the reductions
in these drivers are quite significant: if_cdce.c is reduced from
1000 lines to 320 lines, and if_axen is reduced from 1902 lines
to 1021 lines.
add a "usbnet" module and make the if_axen module depend upon it.
