Subject: [PATCH] iscsi tools: Bug fix on IPC address copy (version 2)
This patch merges Yufei Ren <yufei.ren@stonybrook.edu> patch
with comments from the list plus what I think is a bug in the
addr_len usage.
For the addr_len use, it looks like we were using that as the
arg to memcpy, but that value included the length of the pathname
string and also the offset of sun_path in the sockaddr_un and so
that is too long.

Subject: [PATCH] iscsiadm: Use '-x' option instead of '-v' to specify
chap_tbl_idx
Make appropriate changes to use -x option for chap_tbl_idx cmdline
param. This is done because -v option is used along with -n option
to get the name/value pair.
