net: drop the weight argument from netif_napi_add

2022-09-29T01:57:14Z

We tell driver developers to always pass NAPI_POLL_WEIGHT as the weight to netif_napi_add(). This may be confusing to newcomers, drop the weight argument, those who really need to tweak the weight can use netif_napi_add_weight().

net: ethernet: move from strlcpy with unused retval to strscpy

2022-08-31T21:11:26Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

eth: remove remaining copies of the NAPI_POLL_WEIGHT define

2022-04-30T13:00:45Z

Defining local versions of NAPI_POLL_WEIGHT with the same values in the drivers just makes refactoring harder. This patch covers three more drivers which I missed in commit 5f012b40ef63 ("eth: remove copies of the NAPI_POLL_WEIGHT define"). Signed-off-by: Jakub Kicinski Signed-off-by: David S. Miller

net: ena: Do not waste napi skb cache

2022-02-01T05:36:21Z

By profiling, discovered that ena device driver allocates skb by build_skb() and frees by napi_skb_cache_put(). Because the driver does not use napi skb cache in allocation path, napi skb cache is periodically filled and flushed. This is waste of napi skb cache. As ena_alloc_skb() is called only in napi, Use napi_build_skb() and napi_alloc_skb() when allocating skb. This patch was tested on aws a1.metal instance.

2022-01-08T03:25:51Z

Add qid and req_id to error prints when ENA_REGS_RESET_INV_TX_REQ_ID reset occurs. Switch from %hu to %u, since u16 should be printed with %u, as explained in [1].

net: ena: Remove ena_calc_queue_size_ctx struct

2022-01-08T03:25:51Z

This struct was used to pass data from callee function to its caller. Its usage can be avoided. Removing it results in less code without any damage to code readability. Also it allows to consolidate ring size calculation into a single function (ena_calc_io_queue_size()). Signed-off-by: Shay Agroskin Signed-off-by: Arthur Kiyanovski Signed-off-by: Jakub Kicinski

net: ena: Move reset completion print to the reset function
