[PATCH] net/ice: allow setting CIR

[markus.theil at tu-ilmenau.de]

From: Michael Rossberg <michael.rossberg at tu-ilmenau.de>

ice only allowed to set peak information rate (PIR), while the hardware
also supports setting committed information rate (CIR). In many use
cases both values are needed, therefore add support for CIR.
