It will be pushed if I get no objections before 07/17/24. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/bluca/dpdk-stable This queued commit can be viewed at: https://github.com/bluca/dpdk-stable/commit/4999f309fb5e219d331854190882883828968924 Thanks. Luca Boccassi --- >From 4999f309fb5e219d331854190882883828968924 Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Thu, 11 Jul 2024 17:57:28 +0100 Subject: [PATCH] net/ice: fix sizing of filter hash table [ upstream commit 15800bfdac939e2056c76e7c634825bb682e334c ] The hash table used for managing the filter rules in the ice driver was dimensioned to a hard-coded 16k, which is insufficient for holding all the filters supported by E830 HW. Rather than using a hard-coded value which may need updates for new hardware support, we can query the NIC max filter support from hardware and scale the hash table size based on that value.
