For the SDR entry below, it should have read 5, then 16, then 16.
Here's a grep from one of my systems of the debug output as an example.
pwopr3: [ 5h] = bytes_to_read[ 8b]
pwopr3: [ 10h] = bytes_to_read[ 8b]
pwopr3: [ 10h] = bytes_to_read[ 8b]
pwopr3: [ 1h] = bytes_to_read[ 8b]
pwopr3: [ 5h] = bytes_to_read[ 8b]
pwopr3: [ 10h] = bytes_to_read[ 8b]
pwopr3: [ 10h] = bytes_to_read[ 8b]
pwopr3: [ 1h] = bytes_to_read[ 8b]
pwopr3: [ 5h] = bytes_to_read[ 8b]
BTW, acknowledged that the re-reading of the header is quite
inefficient. Probably legacy code. I should investigate fixing that.

I specifically chose 16 bytes as the default SDR read chunk size b/c
there were some motherboards that could not handle something larger than
that. The code in FreeIPMI is a bit smarter now, moving to smaller
partial-read sizes if the motherboard cannot handle a larger read chunk.
I should reinvestigate this to see if I can improve this, although I'm
scared I will break FreeIPMI on some motherboards. I don't trust a lot
of motherboards to return the right completion code ... sigh :-(
