[Click] Packet alignment

[Sascha Alexander Jopen]

Hey,

I have a question regarding the click packet data alignment.

I have an element which generates packets with 46 bytes of headroom
followed by some data. The whole packet gets aligned in memory, but
data() points to a memory section which is 2 bytes off the alignment on
a 32bit machine. This packet will eventually be pushed into an
UDPIPEncap element. On some architectures (where
HAVE_INDIFFERENT_ALIGNMENT is not defined) a 4-byte alignment is
expected (see line 94 udpipencap.cc). However, click-align does not
insert an Align element on those architectures. If i do this manually,
everything is fine. How can i make click-align insert the Align element?

Thanks in advance,
Sascha
