Don Lewis a35e7eaa1a Always set the hardware parse bit in the IPCB structure when this ... structure, which is new to the 82550 and 82551, is used to transmit a packet. This appears to fix the packet truncation problem that was observed when using 82550-based fxp cards to transmit ICMP or fragmented UDP packets of certain lengths which only had one to three bytes in the second and final mbuf of the packet. This matches a note in the "Intel 8255x 10/100 Mbps Ethernet Controller Family Open Source Software Developer Manual", which says that the hardware parse bit should be set when sending these types of packets. There have also been unconfirmed reports of similar problems when transmitting TCP packets, which should not be affected by the above mentioned change because the hardware parse bit was already being set if the stack requested hardware checksumming of the packet. If the problem remains, the use of the IPCB structure can be disabled to cause the driver to fall back to using the older 82559 interface with 82550-based cards by setting hint.fxp.UNIT_NUMBER.ipcbxmit_disable to a non-zero value at boot time, or using kenv to set this variable before using kldload to load the fxp driver.
