Commit Message

Jakub Kicinski April 27, 2022, 3:40 p.m. UTC 
Defining local versions of NAPI_POLL_WEIGHT with the same
values in the drivers just makes refactoring harder.

Drop the special defines in a bunch of drivers where the
removal is relatively simple so grouping into one patch
does not impact reviewability.
