rtlwifi: Improve handling of IPv6 packets
[ Upstream commit c8f0345586694a33f828bc6b177fb21eb1702325 ]
Routine rtl_is_special_data() is supposed to identify packets that need to
use a low bit rate so that the probability of successful transmission is
high. The current version has a bug that causes all IPv6 packets to be
labelled as special, with a corresponding low rate of transmission. A
complete fix will be quite intrusive, but until that is available, all
IPv6 packets are identified as regular.
This patch also removes a magic number.
