Subject: use -ffunction-sections, -fdata-sections and --gc-sections
In combination with kernel symbol export stripping this significantly reduces
the kernel image size. Used on both ARM and MIPS architectures.

From dd109ded2b526636fff438d33433ab64ffd21583 Mon Sep 17 00:00:00 2001
From: Georgi Valkov <gvalkov@abv.bg>
Date: Fri, 16 Apr 2021 20:44:36 +0300
Subject: [PATCH] ipheth: fix EOVERFLOW in ipheth_rcvbulk_callback
When rx_buf is allocated we need to account for IPHETH_IP_ALIGN,
which reduces the usable size by 2 bytes. Otherwise we have 1512
bytes usable instead of 1514, and if we receive more than 1512
bytes, ipheth_rcvbulk_callback is called with status -EOVERFLOW,
after which the driver malfunctiones and all communication stops.
Fixes: ipheth 2-1:4.2: ipheth_rcvbulk_callback: urb status: -75
