[dpdk-dev] [PATCH v1] baseband/acc100: fix 4GUL outbound size when CRC is dropped

[Nicolas Chautru]

This patch fixes the issue by adjusting the outbound size after
turbodecoding when the appended CRC is meant to be dropped.

Fixes: f404dfe35cc3 ("baseband/acc100: support 4G processing")
Cc: stable@dpdk.org
