Subject: [PATCH] net: enetc: check the index of the SFI rather than the handle
References: bsc#1012628
Patch-mainline: 6.3.3
Git-commit: 299efdc2380aac588557f4d0b2ce7bee05bd0cf2
[ Upstream commit 299efdc2380aac588557f4d0b2ce7bee05bd0cf2 ]
We should check whether the current SFI (Stream Filter Instance) table
is full before creating a new SFI entry. However, the previous logic
checks the handle by mistake and might lead to unpredictable behavior.
Fixes: 888ae5a3952b ("net: enetc: add tc flower psfp offload driver")
