From c4c66f6b119d7c62f8a1467bf8f2cf06f1e01a0d Mon Sep 17 00:00:00 2001 From: Benjamin Lin Date: Wed, 17 Apr 2024 10:47:08 +0800 Subject: [PATCH] wifi: mt76: mt7915: add dummy HW offload of IEEE 802.11 fragmentation Currently, CONNAC2 series do not support encryption for fragmented Tx frames. Therefore, add dummy function mt7915_set_frag_threshold() to prevent SW IEEE 802.11 fragmentation.
