Hm... You're right. I'm going to retract some things.
1) I didn't end up adding a special case handling for this, I only
wanted to but never got around to it.
2) Also these aren't *that* common as I was thinking. They're mostly
limitted to emulex.
drivers/net/ethernet/emulex/benet/be_cmds.c
3173
3174 be_wrb_cmd_hdr_prepare(&req->hdr, CMD_SUBSYSTEM_COMMON,
^^^^^^^^^
First element.
3175 OPCODE_COMMON_SET_HSW_CONFIG, sizeof(*req), wrb,
^^^^^^^^^^^^
Here is the sizeof().
3176 NULL);
3177
3) It's also obvious why emulex would do this because the req struct
could be defined a lot of different ways so long as the first element
is a header. It's like a union.
Sorry for the misinformation. My bad.

dan carpenter
