commit 564fae94d791a9d013edf1cbf84f97f83227c29a Author: Alan Carvalho de Assis <[email protected]> AuthorDate: Sun May 3 15:57:35 2026 -0300 net/sixlowpan: Fix protosize to 16-bit There was another small issue on sixlowpan_input.c code, it was processing protosize and 8-bit instead of 16-bit. It was working because the max tcp->tcpoffset was 0xf0, so protosize = ((uint16_t)tcp->tcpoffset >> 4) << 2; Will be protosize = 15 * 4 = 60 and will fit inside 8-bit. Signed-off-by: Alan C.
