From e4568eac0464ae6d5b361b186b1ee6eb7bf0bdbb Mon Sep 17 00:00:00 2001 From: Erik Stromdahl Date: Mon, 18 Jun 2018 17:01:29 +0300 Subject: [PATCH] ath10k: replace hardcoded constant with define The hardcoded values used in ath10k_mac_tx_push_pending and ath10k_mac_op_wake_tx_queue set an upper limit of how many packets that can be consumed from the TX queue. HTC_HOST_MAX_MSG_PER_TX_BUNDLE is a proper name for this constant, as the value effectively limits the number of messages that can be consumed in one step. Thus, the value is an upper limit of the number of messages that can be added to a TX message bundle.
