[Click] big endian supporting?

[YenJung Chang]

Hi,

I guess the root cause is the alignment is needed in my big-endian board.
The problem of ETHTYPE could be fixed if I change the data type of _et
from uint16_t to uint32_t in ettstat.hh and srforwarder.hh.
However, another problem followed, it showed "ETTStat srcr/es: failed
checksum" repeatly.
I guess this problem is same with ETHTYPE.

I have tried the tool click-align, but failed. (click-align test.click
> test-align.click)
Is there other way to fix this or have to change all uint16_t to
uint32_t manually?

Thanks in advance.
YJ.
