Subject: [PATCH V2 3.18] rtlwifi: rtl8192se: Fix connection problems
Date: Fri, 7 Nov 2014 10:05:12 -0600 [thread overview]
Message-ID: <1415376312-27158-1-git-send-email-Larry.Finger@lwfinger.net> (raw)
Changes in the vendor driver were added to rtlwifi, but some updates
to rtl8192se were missed, and the driver could neither scan nor connect.
There are other changes that will enhance performance, but this minimal
set fix the basic functionality.
Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net>

V2 - As requested by John Linville, the patch was reduced to its bare essentials
as the first version was too large to be a fix.
