Subject: [PATCH ethtool-next 07/14] sff-8636: Use memory map during parsing
From: Ido Schimmel <idosch@...dia.com>
Instead of passing one large buffer to the individual parsing functions,
use the memory map structure from the previous patch.
This has the added benefit of checking which optional pages are actually
available and it will also allow us to consolidate the IOCTL and netlink
parsing code paths.
Tested by making sure that there are no differences in output in both
the IOCTL and netlink paths before and after the patch.
