New Revision: 261541
URL: http://svnweb.freebsd.org/changeset/base/261541
Log:
Import USB RNDIS driver to FreeBSD from OpenBSD.
Useful for so-called USB tethering.
- Imported code from OpenBSD
- Adapted code to FreeBSD
- Removed some unused functions
- Fixed some buffer encoding and decoding issues
- Optimised data transport path a bit, by sending multiple packets at a time
- Increased receive buffer to 16K
Obtained from: OpenBSD
