Some additional information (my wireshark was not validating checksums, so
I missed the real culprit).

It so appears, that when timestamps are enabled on my dev board, TCP
checksum in SYN packet turns out to be incorrect. That's why those packets
are dropped by the remote side. When TCP timestamps are disabled, checksums
are correct.

Any ideas where this particular problem may originate?
