[PATCH 06/10] ath10k: Add support for htt_data_tx_desc_64 descriptor
Govind Singh

Thu Dec 21 01:00:55 PST 2017
WCN3990 target uses 64 bit frags_paddr in htt tx descriptor,
which holds the physical address of SKB fragments in tx data path.
In order to support 64 bit bit frags_paddr in htt tx descriptor, define
htt_data_tx_desc_64 descriptor and ath10k_htt_tx_64 method for handling
tx data path with new descriptor fields.
