Description of problem:
When running very heavy UDP Tx stress traffic with 10/100 adapters, load-
sharing collapses to only one slave after a few seconds. Caused by a 
unsigned/signed cast error in the TLB code.

Version-Release number of selected component (if applicable):
kernel-2.4.20-1.1931.2.231.2.11.ent

How reproducible:
Configure a bond team with only 10/100 adapters and run very heavy UDP Tx 
stress traffic to many clients. Monitor Tx/Rx activity of the slaves.

Steps to Reproduce:
1. insmod bonding mode=5
2. ifconfig bond0 <ip-addr>
3. ifenslave bond0 eth0 eth1 eth2
4. start stress application (e.g iperf, netperf, etc.)
    
Actual results:
After a few seconds only one slave takes part of load sharing while others stay 
idle. Traffic may pass from slave to slave at 10 sec. intervals (re-balance 
timeout).

Expected results:
All slaves continuously take part of the load sharing.

Additional info:
A bug fix patch was sent by me on June 26th to bond-devel, linux-net and linux-
netdev lists. It was already accepted by Jeff Garzik into his net-drivers-2.4 
BK tree.
