From f737b70434f332042fcbe37f85ee3ee424959403 Mon Sep 17 00:00:00 2001 From: Avraham Stern Date: Wed, 5 Jun 2024 13:57:16 +0300 Subject: [PATCH] wifi: nl80211: remove the FTMs per burst limit for NDP ranging In NDP ranging, the number of NDP exchanges is not negotiated and thus is not limited by the protocol. Remove the limit on FTMs per burst for trigger based and non trigger based ranging.
