[Click] CLICK_BYTE_ORDER

[Koen Beel]

One more thing:

Why would one use e.g. (see elements/ip/checkipheader.hh):
'bool _verbose : 1;'   ?
This is a bool bitfield, but why not use just 'bool _verbose;' ? Like
'bool _checksum;' in checkipheader.hh
Is't the bool bitfield slower because of the use of bitmasks?
