This seems to be the\n'num_stations' in 'struct ath11k' that did not get reset properly in\nthis case. In ath11k_mac_op_start(), it was indeed the only accounting var\nthat did not get reset so let's clear it too.\n\nThis avoids problems like those:\n\n\t[1248828.088023] WARNING: CPU: 0 PID: 12281 at net/mac80211/util.c:1682 ieee80211_reconfig_stations+0x98/0xc0\n\t[1248828.088115] Call trace:\n\t[1248828.088116]  ieee80211_reconfig_stations+0x98/0xc0 (P)\n\t[1248828.088119]  ieee80211_reconfig+0x774/0x1438\n\t[1248828.088123]  ieee80211_restart_work+0x10c/0x178\n\t[1248828.088127]  process_one_work+0x178/0x3c0\n\t[1248828.088130]  worker_thread+0x280/0x440\n\t[1248828.088133]  kthread+0xe0/0xf8\n\t[1248828.088137]  ret_from_fork+0x10/0x20\n\t[1248828.088141] ---[ end trace 0000000000000000 ]---\n\t[1248836.686604] ath11k_pci 0000:04:00.0: refusing to associate station: too many connected already (128)\n\t[1248836.686609] ath11k_pci 0000:04:00.0: Failed to add station: xx:xx:xx:xx:xx:xx for VDEV: 1\n\nTested-on: QCN9074 hw1.0 PCI WLAN.HK.2.9.0.1-01977-QCAHKSWPL_SILICONZ-1",
