I didn't look at whether it's easy to create symlinks in sysfs.  I
don't really see any problem with just having both mlx4_ib and
mlx4_eth export the same data, and in fact that may make sense if
there is a different way mlx4_eth might want to export it (ethtool?).

However I definitely don't think we should force all userspace tools
to look in two different places in sysfs for information.  And if
there are some attributes that all devices support, then I guess we
should move the implementation of those attrs into core/sysfs.c.
