[PATCH net-next v3 08/12] net: stmmac: Pass stmmac_priv in some callbacks

From: Andrew Halaney
Date: Fri Mar 31 2023 - 17:49:02 EST

Next message: Andrew Halaney: "[PATCH net-next v3 09/12] net: stmmac: dwmac4: Allow platforms to specify some DMA/MTL offsets"
Previous message: Andrew Halaney: "[PATCH net-next v3 05/12] net: stmmac: Remove unnecessary if statement brackets"
In reply to: Andrew Halaney: "[PATCH net-next v3 05/12] net: stmmac: Remove unnecessary if statement brackets"
Next in thread: Andrew Halaney: "[PATCH net-next v3 09/12] net: stmmac: dwmac4: Allow platforms to specify some DMA/MTL offsets"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

Passing stmmac_priv to some of the callbacks allows hwif implementations
to grab some data that platforms can customize. Adjust the callbacks
accordingly in preparation of such a platform customization.

This patch (and the following patch) are replacements for
https://lore.kernel.org/netdev/20230320204153.21736840@xxxxxxxxxx/
as was requested. Hopefully I was understanding the intent correctly :)

Changes since v2:
* New, replacing old wrapper approach
