From b7573a0a27bfa8270dea9b145448f6884b7cacc1 Mon Sep 17 00:00:00 2001 From: Tsang-Shian Lin Date: Sat, 9 Dec 2017 11:37:10 -0600 Subject: rtlwifi: rtl_pci: Fix the bug when inactiveps is enabled. Reset the driver current tx read/write index to zero when inactiveps nic out of sync with HW state. Wrong driver tx read/write index will cause Tx fail.
