For the 82599 NI= C, the EtherType value of each EtherType filter should be passed in little = endian order according to the 82599 datasheet. I wonder whether this is the= case with all NICs that support the EtherType filter? From the link here h= ttp://dpdk.org/doc/guides/nics/overview.html, I get the list of networking = drivers that support EtherType filters. Could anyone point me some hints on this? Thanks. Best, Qiaobin
