Hi all,
Sorry for the typo in the subject.  It is enicpmd.

Bruce,
Please try out this patch on FreeBSD and let me know if any fix is
required.

Thanks,
-Sujith

Actually no, it should be enic.
For virtio, it is not virtiopmd, for ixgbe, it is not ixgbepmd, etc :)
Talking about title, please start with lower case and a verb, e.g. fix build 
with clang.
To have a good idea of title formatting, you could check at the git history.

Thanks

Usually we use enic to denote the kernel mode driver and enicpmd to denote
the PMD.
But it is alright to follow what¹s being done in the community.  I shall
use enic from now on.

This PMD now compiles up with clang on FreeBSD. The patch seems rather large though,
are all these changes necessary for clang compilation?

On the basis that this fixes the issue though:
