The is= sue is that this card requires "options INET6" in the kernel, but this is *not* documented anywhere in MLX4EN(4)! This really needs to be documented for a= few reasons: 1. Other cards that have similar IPv6 only options do not display this beha= vior when IPv6 is removed from the kernel. For example, look at the overlap in options between this card and an igb interface: igb options=3De507bb mlxen options=3Ded07bb They are nearly identical, yet the igb interface will continue to work with= out IPv6 while the mlxen will not. 2. There is no hint anywhere that I can see, in dmesg, ifconfig, or even Mellanox's own software (mst) that this is the cause when your interface doesn't appear. 3. Some of us still live in the one country that hates IPv6 and thus aren't= in the habit of keeping it in our kernels. I'll reassign the PR to documentation. --=20 You are receiving this mail because: You are on the CC list for the bug.=
