If anyone has any objections, please let me know. ------------------ From: Yedidya Benshimol [ Upstream commit ac0c6fdc4c56b669abc1c4a323f1c7a3a1422dd2 ] During the D3 resume flow, all new rekeys are passed from the FW. Because the FW supports only one IGTK at a time, every IGTK rekey update should be done by removing the last IGTK. The mvmvif holds a pointer to the last IGTK for that reason and thus should be updated when a new IGTK is passed upon resume.
