[Openib-windows] [PATCH] read guids from flash

[Yossi Leybovich]

Fab

attached patch h to read the GUID with query_ca and not directly read it
from the flash.
We encounter problem with new boards that have different sector size and the
driver could not read the GUID

(we should provide patch that will also get the sector size from the board
and assume it as define to 20000)
