Zeeb AuthorDate: 2022-06-26 19:13:00 +0000 Commit: Bjoern A. Zeeb CommitDate: 2022-06-26 19:13:00 +0000 LinuxKPI: 802.11: cleanup lsta better This changes cleans up lsta from the VIF station list as well as deals with freeing the lsta itself so it is not leaked. lkpi_iv_update_bss() makes this more complicated than it should be as we ties more sta state (incl. drv/fw) to the node that net80211 does not know about. There is more work to be done detangling this now that is better understood.
