Subject: [PATCH v2 3/3] ath10k: Request credit report if flow control enabled on ep
Date: Fri, 12 Oct 2018 15:19:38 +0530	[thread overview]
Message-ID: <20181012094938.14734-4-govinds@codeaurora.org> (raw)
In-Reply-To: <20181012094938.14734-1-govinds@codeaurora.org>

FW credit flow control is enabled for only WMI ctrl
service(CE3) but credit update is requested unconditionally
on all HTC services as part of HTC tx in CE3/CE0/CE4.

This is causing WOW failure as FW is not expecting credit
report request on other end-points(CE0/CE4).

Request credit report only on those endpoints where
credit flow control is enabled.

Testing:
    Tested on WCN3990 HW.
    Tested FW: WLAN.HL.2.0-01192-QCAHLSWMTPLZ-1.
