From 06470f7468c8b6c95e72ebda803a61a99f4ee446 Mon Sep 17 00:00:00 2001 From: Sara Sharon Date: Thu, 28 Jan 2016 16:19:25 +0200 Subject: mac80211: add API to allow filtering frames in BA sessions If any frames are dropped that are part of a BA session, the reorder buffer will "indefinitely" (until the timeout) wait for them to come in (or a BAR moving the window) and won't release frames after them. This means it isn't possible to filter frames within a BA session in firmware. Introduce an API function that allows such filtering. Calling this function will move the BA window forward to the new SSN, and allows marking frames after the SSN as having been filtered, so any future reordering activity will release frames while skipping the holes.
