[PATCH net-next v2 00/15] remove copies of the NAPI_POLL_WEIGHT define

[PATCH net-next v2 00/15] remove copies of the NAPI_POLL_WEIGHT define

[Jakub Kicinski]

netif_napi_add() takes weight as the last argument. The value of
that parameter is hard to come up with and depends on many factors,
so driver authors are encouraged to use NAPI_POLL_WEIGHT.

We should probably move weight to an "advanced" version of the API
(__netif_napi_add()?) and simplify the life of most driver authors.

In preparation for such API changes this series removes local
defines equivalent to NAPI_POLL_WEIGHT from drivers, so that a simple
coccinelle / spatch script does not get thrown off by them.

v2:
 - drop staging bits (patch 2)
 - fix subject (patch 8)
 - add qeth change (patch 15)

[PATCH net-next v2 01/15] eth: remove copies 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.

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

[PATCH net-next v2 01/15] eth: remove copies 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.

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