Subject: [Intel-wired-lan] [PATCH iwl-net v1 4/5] igc: Reduce retry count to a more reasonable number
Date: Tue, 6 Aug 2024 17:30:31 -0700 [thread overview]
Message-ID: <20240807003032.10300-5-christopher.s.hall@intel.com> (raw)
In-Reply-To: <20240807003032.10300-1-christopher.s.hall@intel.com>
From: Christopher S M Hall <christopher.s.hall@intel.com>
Setting the retry count to 8x is more than sufficient. 100x is unreasonable
and would indicate broken hardware/firmware.
Fixes: a90ec8483732 ("igc: Add support for PTP getcrosststamp()")
Signed-off-by: Christopher S M Hall <christopher.s.hall@intel.com>
