I noticed from an installation which i made for trunking between a HP Procurve switch and some ESX servers. So after some weeks with issues I found a solution to get rid of Dropped TX packets.
The following you will need to configure on your Switch. ( i used a HP Procurve switch 4208GL )
As you see I used flow-control You need to configure this option first in the global configuration mode.
You need to create a trunk
trunk D5-D8 Trk2 Trunk
A VLAN configuration need to be changed.
untagged < un tagged interfaces > ,Trk2
ip address < ip address >
no untagged < no untagged interfaces >
The trunk(s) needs to be added to the default VLAN
Further you have to configure Spanning-Tree on the switch for the Trk2 ( in this case )
spanning-tree Trk2 priority 4
After this change you will see no packets are dropped any more on this trunk.
In an other article i will describe the settings for the ESX server

Thanks for that. I have this Problem too.
I am waiting for the next part on the settings on ESX server
