Subject: [PATCH] ath10k: Increase AST table SKID length limit
Date: Thu, 12 Feb 2015 14:58:42 +0530	[thread overview]
Message-ID: <1423733322-31113-1-git-send-email-sjegadee@qti.qualcomm.com> (raw)

The current SKID length configuration causes firmware
to reject peer creation for not able to allocate
AST entries for peers. This issue is observed when
least significant 3 bytes are used ramdomly to create
client MAC addresses.

AST table SKID length configuration is increased to
maximum value to fix this issue.
