Subject: [PATCH net-next 1/2] igc: Simplify setting flags in the TX data descriptor

From: Vinicius Costa Gomes <vinicius.gomes@...el.com>

We can re-use the IGC_SET_FLAG() macro to simplify setting some values
in the TX data descriptor. With the macro it's easier to get the
meaning of the operations.
