Subject: [net-next 08/17] igc: Fix NFC rules leak when driver is unloaded
Date: Fri, 22 May 2020 19:51:00 -0700 [thread overview]
Message-ID: <20200523025109.3313635-9-jeffrey.t.kirsher@intel.com> (raw)
In-Reply-To: <20200523025109.3313635-1-jeffrey.t.kirsher@intel.com>
From: Andre Guedes <andre.guedes@intel.com>
If we have RFC rules in adapter->nfc_rule_list when the IGC driver
is unloaded, all rules are leaked. This patch fixes the issue by
introducing the helper igc_flush_nfc_rules() and calling it in
igc_remove(). It also updates igc_set_features() so is reuses the
new helper instead of re-implementing it.
