[lwip-devel] [PATCH] Avoid warnings about ignored packed attributes

[David Woodhouse]

I get a whole bunch of warnings along these lines:
 warning: ‘packed’ attribute ignored for field of type ‘struct ip_hdr’

If the struct is marked as packed, there should be no need to mark each
member as packed too...
