From 37949932b4c8854d8122ac385bfcab725440625c Mon Sep 17 00:00:00 2001
From: Jes Sorensen <Jes.Sorensen@redhat.com>

Subject: [PATCH] rtl8xxxu: Use flag to indicate whether device has TX report
timer support
Use a fileops flag to indicate whether the device has TX report timer
support. This will make it easier to include future devices such as
8188eu to use the TX report timer.
