From 9c99e124a279391dbe2cef66226fd4e86bde8f4d Mon Sep 17 00:00:00 2001
From: Maharaja Kennadyrajan <mkenna@codeaurora.org>

Subject: [PATCH 1/2] ath11k/mac80211: Add support to account memory stats

Memory allocations in the driver & mac80211 are logged
and populate those values to the user space via debugfs.
This stats will give the snapshot of the memory being
used by the driver at the time of dumping these
memory stats.

Command:
cat /sys/kernel/debug/ath11k/ipq8074\ hw2.0/memory_stats

Sample output of the stats
MEMORY STATS IN BYTES:
malloc size : 6287583
ce_ring_alloc size: 109308
dma_alloc size:: 10831860
htc_skb_alloc size: 3840
wmi alloc size: 0
per peer object: 4644
rx_post_buf size: 5091840
Total size: 22329075

User can disable/enable the memory stats accounting with
the below command.

echo N > /sys/kernel/debug/ath11k/ipq8074\ hw2.0/enable_memory_stats
where N = 0 to disable logging, 1 to enable the logging.

Note: This should be enabled/disabled only after wifi is down.
User shouldn't enable/disable when the wifi is up to avoid
accounting the negative values which cause incorrect values
in the memory stats.

Command:

cat /sys/kernel/debug/ieee80211/phyX/memory_stats
memory stats: malloc_size: 108
