Subject: [PATCH net-next 05/10] sfc: Use strlcpy() to copy ethtool stats
 names

Fix CID 113703 in the Coverity report on Linux.

ethtool stats names are limited to 32 bytes including a null
terminator.  Use strlcpy() to ensure that we will always include the
null terminator even if a source string becomes longer than this.
