Subject: [PATCH net-next v2 2/6] net: qualcomm: rmnet: Remove the some redundant macros

From: Subash Abhinov Kasiviswanathan <[email-masked]>
Date: Sat, 9 Dec 2017 13:58:26 -0700

Multiplexing is always enabled when transmiting from a rmnet device,
so remove the redundant egress macros. De-multiplexing is always
enabled when receiving packets from a rmnet device, so remove those
ingress macros.
