[dpdk-users] Endianness of the EtherType value of EtherType filters

Indeed, I have checked the source code of three DPDK networking drivers: i40e, ixgbe, e1000. And all of them use little endian order. I didn’t find the parts for other drivers. I wonder whether it’s true for the other drivers, like bnxt, i40e…vec, igb, ixgbe…vec, etc. or will they be supported with little endian order in the future if not implemented yet? Thanks a lot.

Currently, I am using the EtherType filters in our system. For the 82599 NIC, 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 http://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.
