[dpdk-users] Get interface speed through IOCTL

Hi,
I need to get the interface speed though standard IOCTL call:
edata.cmd = ETHTOOL_GSET;
// issue ioctl
rc = ioctl(sock, SIOCETHTOOL, &ifr);
However, for 10G interface I do not read a correct speed, since it may
not be supported.
Out 1G cards are I350 and 10G card is I40.
After going through the source, I cam across the function
igb_get_settings()
{
ecmd->supported = (SUPPORTED_10baseT_Half| ...| .... );
switch(adapter->link_speed) {
case SPEED_1000:
case SPEED_2500:
//etc etc.
}
}
There is no support for 10000base. So to get the ioctl working for 10G
card, is it a trivial change of adding few more support options and
adding another case SPEED_10000 clause, or is it more involved ?
Thanks
