From 78884187c09fbd41b6c0a4d1a0da6571df381ddb Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Mon, 22 Apr 2024 17:25:58 +0200 Subject: [PATCH] mlxsw: spectrum_acl_tcam: Rate limit error message [ Upstream commit 5bcf925587e9b5d36420d572a0b4d131c90fb306 ] In the rare cases when the device resources are exhausted it is likely that the rehash delayed work will fail. An error message will be printed whenever this happens which can be overwhelming considering the fact that the work is per-region and that there can be hundreds of regions. Fix by rate limiting the error message.
