[OEM-B][SRU][PATCH 01/11] UBUNTU: SAUCE: rsi: Fix for low throughput issue

[Shrirang Bagul]

From: Siva Rebbagondla <siva.rebbagondla at redpinesignals.com>

BugLink: https://bugs.launchpad.net/bugs/1782070

During verification, we have observed low throughput rates with this
driver. This is because, Qos enable flag is overridden by sequence
number in the data descriptor frame.
