iscsi_ibft: Add prefix-len attr and display netmask
The iBFT table only specifies a prefix length, not a netmask. And the netmask is pretty much pointless for IPv6. So introduce a new attribute 'prefix-len'. Some older user-space code might rely on the netmask attribute being present, so we should always display it. Changes from v1: - Combined two patches into one Changes from v2: - Cleaned up/corrected wording for patch description Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Lee Duncan <lduncan@suse.com> Reviewed-by: Mike Christie <michaelc@cs.wisc.edu> Signed-off-by: Konrad Rzeszutek Wilk <konrad@kernel.org>
