[PATCH wireless-next 0/3] wifi: remove copies of the NAPI_POLL_WEIGHT define

[Jakub Kicinski]

This is prep for a small refactoring of the netif_napi_add() API.

Jakub Kicinski (3):
  wifi: rtw88: remove a copy of the NAPI_POLL_WEIGHT define
  wifi: ath10k: remove a copy of the NAPI_POLL_WEIGHT define
  wifi: wil6210: use NAPI_POLL_WEIGHT for napi budget

[PATCH wireless-next 1/3] wifi: rtw88: remove a copy of the NAPI_POLL_WEIGHT define

[Jakub Kicinski]

Defining local versions of NAPI_POLL_WEIGHT with the same
values in the drivers just makes refactoring harder.

[PATCH wireless-next 3/3] wifi: wil6210: use NAPI_POLL_WEIGHT for napi budget

[Jakub Kicinski]

The comment next to WIL6210_NAPI_BUDGET says "arbitrary".
If we're picking arbitrary values let's pick the recommended
default which is NAPI_POLL_WEIGHT.

This failed to build as recently usb.c got napi poll as well, I fixed it
in the pending branch:
