** Description changed:

  Hello,
  
  when sending larger amounts of data (SCP, NFS, printjobs), the wired
  network produces errors. SCP fails with "Corrupted MAC on input", NFS
  just stops tranfering. The network card in question is a Broadcom
  BCM5906M build into a S10e Lenovo netbook using the "tg3" kernel module.
  
  I've tested this on 2 different S10e netbooks, on different networks, to
  rule out a broken network card or network equipment. Sending the same
  files over the wireless interface works, and incoming traffic is also no
  problem.
  
  The MTU is set to 1500 (ethernet standard), which works on every other
  machine in the same network.
  
  When lowering the MTU (e.g. to 1000) the network card works without
- problems, so I suspect the network driver has problems with large
- packages.
+ problems, so I suspect the network driver has problems with sending
+ large packets.
  
  This bug is send via the ubuntu-bug utility filed agains the kernel, so
  I hope every neccesary information was automaticly attaced.
  
  P.S.:
  
  - A friend running 10.04 beta on the same hardware also has this problem.
  - Bug #372685 is similar to this one (but old and incomplete?).
