Subject: [PATCH] wil6210: support max aggregation window size 64
Git-commit: 1b99197dc00cbb34cb39be70ad5beb4a5a84be4b
Patch-mainline: v4.19-rc1
References: FATE#326906
FW can support BACK window size 64 for performance improvements.
A new FW capability is added for notifying the host on the increased
max BACK win size support.
Defining WIL_MAX_AGG_WSIZE_64 and WIL_MAX_AMPDU_SIZE_128 to be used
in this case.
