I was testing the wx driver with an 82544 based NIC. Small packets were used to allow very high packet rates. I was experimenting with various values of RIDV. The problem I experienced was 82544 chip lockup when RIDV was nonzero and packet rate was high. Small packets were never a problem by themselves.
