Subject: [PATCH ath-devel] wifi: ath: split 5150-5350 regulatory rule
Date: Thu, 3 Sep 2026 19:25:57 -0700 [thread overview]
Message-ID: <20260904022557.2679261-1-rosenp@gmail.com> (raw)
Allow initiation in the 5150-5240 MHz portion of the world
regulatory rule while retaining NO_IR for 5260-5350 MHz, where
radar detection is required.
The previous single rule marked both ranges NO_IR and unnecessarily
restricted channels 36-48. Update the rule counts for the expanded
rule list.
