5.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Felix Fietkau <nbd@nbd.name>
commit 906d2d3f874a54183df5a609fda180adf0462428 upstream.
Since ccmp_pn is u8 *, the second half needs to start at array index 4 instead of 0. Fixes a connection stall after a certain amount of traffic
