[PATCH] ath9k: Add support for OCB mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The patch adds support for "outside the context of a BSS"(OCB) mode
to ath9k driver and extends debugfs files by OCB ralated information.

This patch was tested on AR9380-AL1A cards.
