Hi Kalle,

The ath10k-check warning has been corrected and I have sent the v2 for 
the same.


Thanks,
Rakesh Pillai.

in the wcn3990 firmware the checksum is incorrect in the TCP/UDP packets
and all patckets are dropped. But due note that wcn3990 support in

[PATCH] ath10k: Enable hw checksum for wcn3990

2018-04-05 Thread pillair
From: Rakesh Pillai 

By default ath10k driver enables the support for HW_CHECKSUM
(NETIF_F_HW_CSUM). Since the TCP/UDP checksum calculation is not enabled
in the wcn3990 firmware the checksum is incorrect in the TCP/UDP packets
and all patckets are dropped. But due note that wcn3990 support in
ath10k is still incomplete so this isn't a critical fix (yet).

Enable hw checksum calculations in wcn3990 hardware by
setting the proper flags in msdu descriptor tso flags.
