[PATCH 07/17] iwlwifi: mvm: fix reorder timer re-arming

[Luca Coelho]

From: Sara Sharon <sara.sha...@intel.com>

When NSSN is behind the reorder buffer due to timeout
the reorder timer isn't getting re-armed until NSSN
catches up. Fix it.

Fixes: 0690405fef29 ("iwlwifi: mvm: add reorder timeout per frame")
