Hello again,
I have changed bandwidth to 100%, 90% or 95%. Syntax OK, but value stops at 1.27Gbit (it looks, that 1Gbit is default)
When I give ifconfig, I see:
media: Ethernet autoselect (10Gbase-SR <full-duplex,rxpause,txpause>)
It looks that "autodetection" of pf is broken to.
Thank you very much
Radek
