Roundrobin runner of team driver uses 'unsigned int' variable to count
the number of sent_packets. Later it is passed to a subroutine
team_num_to_port_index(struct team *team, int num) as 'num' and when
we reach MAXINT (2**31-1), 'num' becomes negative.
This leads to using incorrect hash-bucket fo

Roundrobin runner of team driver uses 'unsigned int' variable to count the
number of sent_packets.
Later it is passed to a subroutine team_num_to_port_index(struct team *team,
int num) as
'num' and when we reach MAXINT (2**31-1), 'num' becomes negative.

The problem was found on RHEL7.2 but is still present in the latest upstream
kernel (according to visual sources inspection).
While using roundrobin runner we have noticed that after sending on team0 about
2.1 billion packets we started seeing 50% packet drop on team0
(according to 'netstat -i'
