While poking around in the firmware, I noticed what appears to be
an ath10k driver issue, which came in with this commit below.

Those variables above may be correct for some firmware, but they are not
correct for at least some versions of 10.4, which have this instead:
...
A_UINT32 hi_fw_swap; /* 0x104 */
/* host side need to support tx/rx data packet swap */
A_UINT32 hi_txrx_dataswap; /* 0x108 */
/* enable allocram statistics gathering (set to an integer, which
* is the number of tracking records that allocram will allocate).
*/
A_UINT32 hi_allocram_track_max; /* 0x108 */
}
I guess this may not be an issue as long as zero'd values are sent to the
10.4 nics, but it is confusing at best.
Eric, where did you get these values from?
Thanks,
Ben
