Thanks for the update.

There is no need to repost because of this, but in future please keep in
mind that revised patches should:

1. have a revision number, e.g. v2

   Subject [PATCH v2 iwl-next] ...

2. Have some of revision information below the scissors (---)

   v2
   - Updated size calculation to use IFNAMSIZ and izeof(i40e_dbg_command_buf)

3. Be a new thread, as opposed to a reply to an existing thread.

The above notwithstanding, this patch looks good to me.
