Is there an upper limit on a transmit packet size, which has CSUM_TSO bit set in the mp->m_pkthdr.csum_flags field. Browsing the code I thought it was 65535 bytes. However at least on Freebsd 7.x, I am occasionally noticing that the driver is asked to transmit packets which are 65536 and 65537 bytes. Am I missing something?
