net: move ether_crc to tsec driver
ether_crc was added to the core net code in commit 53a5c424bf86 ("multicast tftp: RFC2090") so that other drivers could use it. However the only current user of it is tsec.c so move it there. Signed-off-by: Chris Packham <judge.packham@gmail.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
