This one is attempt to fix the following bug reports on re(4).
- VLAN tagging does not work on multi-fragmented frames.
- Non-working/instability on re(4) hardwares that uses MSI.
- Unconditional VLAN tag stripping without respect to ifconfig
configuration.
- ENOBUFS on transmitting UDP frames under heavy network loads.
- DAC does not work.
This one removed previous checksum offload hack for checksum offload
on PCIe hardwares so I'm not sure checksum offload still work on
PCIe hardwares. Please test and let me know how it goes.
Also make sure you have all hardware features enabled.(checksum
offload, TSO, VLAN hardware tagging etc).
Sorry for the slow answer.
I've tried the new files, and they seem to work:
# ifconfig re0
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>

The only problem I see now is the one I already mention in the last
mail. There are slow packets
in the stream of the communication:

It would be great if you could understand why this happens...
Thanks again.
