This is a note to let you know that I've just added the patch titled
staging: vt6656: Fix pairwise key entry save.
to my staging git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
in the staging-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: staging: vt6656: Fix pairwise key entry save.
The problem is that the group key was saved as VNT_KEY_DEFAULTKEY
was over written by the VNT_KEY_GROUP_ADDRESS index.
mac80211 could not clear the mac_addr in the default key.
The VNT_KEY_DEFAULTKEY is not necesscary so remove it and set as
VNT_KEY_GROUP_ADDRESS.
mac80211 can clear any key using vnt_mac_disable_keyentry.
