This is old code that I just wrapped-up in a routine as a part of this patch, to help
with re-factoring of be_cmd_set_profile_config() needed for vxlan setting.
I'd like to take up any cleanup of this code as a part of a separate patch and not this patch-set.

Also, if you observe the be_nic_res_desc{} struct, the fields that require
re-setting with 0xFFFF (count fields and params that are to remain unchanged)
are all not contiguous. So, just memset-ing a region of memory doesn't necessarily work here.

thanks,
