[PATCH 1/2] revert "mwifiex: enable aggregation for TID 6 and 7 streams"

[Avinash Patil]

This patch reverts 'commit c5534844cdee ("mwifiex:
enable aggregation for TID 6 and 7 streams")'.
TID6 & TID7 is voice traffic which is quite time sensitive.
Do not enable any type of aggregation on these TIDs.

[PATCH 2/2] mwifiex: fix invalid HT IE configuration in FW

[Avinash Patil]

From: Zhaoyang Liu <liuzy@marvell.com>

This patch fixes an issue where it was discovered that driver is setting
invalid HT IEs to FW. This was happening because bug in parsing HT IE.
Driver would incorrectly point to start of HT IE while FW only needs actual
HT configuration - excluding EID and length.
