From 352f5b328262f65e685d72e634d62df37ae64d76 Mon Sep 17 00:00:00 2001 From: Breno Leitao Date: Wed, 6 Mar 2024 06:26:41 -0800 Subject: net: usbnet: Leverage core stats allocator With commit 34d21de99cea9 ("net: Move {l,t,d}stats allocation to core and convert veth & vrf"), stats allocation could be done on net core instead of in this driver. With this new approach, the driver doesn't have to bother with error handling (allocation failure checking, making sure free happens in the right spot, etc). This is core responsibility now. Remove the allocation in the usbnet driver and leverage the network core allocation instead.
