Subject: [Ipoverib] Structure Packing

Hi All,

This question is regarding the packing involved in
Infiniband Protocol Specs Version 1.0a.

Are the Infiniband structures naturally aligned at 8
byte boundaries ?

What I wish to say that if I have a compiler which
doesn't support packing,
then does it make any difference in the size of
structures ?

Also, the structure NodeInfo (Page 663, Table 122) has
a "Reserved" component which is 64 bits.
long. This field is preceded by '4' 8-bit entities.
This will create a hole in the NodeInfo structure.
Is there any specific reason to do so ?

Regards
Lee
