[PATCH] ipvs: Expose ip_vs_ftp module parameters via sysfs.

[PATCH] ipvs: Expose ip_vs_ftp module parameters via sysfs.

[Krzysztof Wilczynski]

This is to expose "ports" parameter via sysfs so it can be read
at any time in order to determine what port or ports were passed
to the module at the point when it was loaded.

Thanks Krzysztof,

I have queued this up locally and will forward it on for inclusion in 3.2
once the kernel.org hiatus is over.
