From 6c7e7da2e0f2141cdc491cd5b9d0b937c08939c9 Mon Sep 17 00:00:00 2001 From: Robert Hancock Date: Tue, 8 Mar 2022 15:10:13 -0600 Subject: [PATCH] net: axienet: Use napi_alloc_skb when refilling RX ring Use napi_alloc_skb to allocate memory when refilling the RX ring in axienet_poll for more efficiency. napi_alloc_skb() can reuse softirq-local cache of freed skbs which may still be cache-warm and skipping allocator calls.
