Subject: [34-longterm 070/247] ieee80211: correct IEEE80211_ADDBA_PARAM_BUF_SIZE_MASK macro

From: Amitkumar Karwar <akarwar@...vell.com>

                   -------------------
    This is a commit scheduled for the next v2.6.34 longterm release.
    If you see a problem with using this for longterm, please comment.
                   -------------------

commit 8d661f1e462d50bd83de87ee628aaf820ce3c66c upstream.

It is defined in include/linux/ieee80211.h. As per IEEE spec.
bit6 to bit15 in block ack parameter represents buffer size.
So the bitmask should be 0xFFC0.
