[ Upstream commit 4701ee5044fb3992f1c910630a9673c2dc600ce5 ]
The TCP header fields seq and ack_seq are 32-bit values in network byte order as (__be32). these fields were earlier printed using ntohs(), which converts only 16-bit values and produces incorrect results for 32-bit fields. This patch is changeing the conversion to ntohl(), ensuring correct interpretation of these sequence numbers.
Notably, the format specifier is updated from %d to %u to reflect the unsigned nature of these fields.
improves the accuracy of debug log messages for TCP sequence and acknowledgment numbers during TX timeouts.
