1/ We cannot really consider code which is not public
2/ You may extend ethdev if some functions are missing
> For this release, we focus on releasing some basic functions (btw, mac_addr_set is not available but is covered by this patch).
Yes, you are extending ethdev by adding rte_eth_dev_default_mac_addr_set.
> The key reason that this set of library is not released as part of ethdev is the ethtool API dependency on kernel include file.
It is a good reason to separate the library.
But it doesn't justify its need.
> To faithfully carry the ethtool ops and net dev ops API parameters, the ethtool APIs are designed to follow the original definition except avoiding carry kernel states.
> With that, to support ethtool APIs faithfully, we need to include <linux/ethtool.h>.
> As suggested by many DPDK veterans including Thomas (indicated over your reply), you would prefer these APIs in a separate library.
I think I'm starting to understand that you really need ethtool conversion
(implemented in rte_ethtool_get_drvinfo) but not the other functions which
are simple wrappers. Right?
