From eb2c11b27c58a62b5027b77f702c15cd0ca38f7d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 28 Feb 2024 17:06:56 +0100 Subject: [PATCH] net: bql: fix building with BQL disabled It is now possible to disable BQL, but that causes the cpsw driver to break: drivers/net/ethernet/ti/am65-cpsw-nuss.c:297:28: error: no member named 'dql' in 'struct netdev_queue' 297 | dql_avail(&netif_txq->dql), There is already a helper function in net/sch_generic.h that could be used to help here. Move its implementation into the common linux/netdevice.h along with the other bql interfaces and change both users over to the new interface.
