Several network-related data structures are defined in gelic_udbg.
These could be easily dropped and the standard ones defined in network
headers could be used instead.

The 4 patches that follow replace ethernet, vlan, ip and udp
structures in gelic_udbg.  Note that this has been compile-tested
only.

A few of these were declared __packed in the gelic driver, while that
attribute isn't used for the standard definitions.

It probably doesn't make a difference, as there are no gaps in the structures
when unpacked, unless pointers to the structures themselves are unaligned.

Thank you for your comments, Geert.  I had noticed those differences,
but the quick code review I did didn't show any issues with that could
be triggered by this change.  But as I referred, I only compile-tested
this code and didn't actually executed it in the real hw.

Cheers,
