My position is let's remove the macro in any way.
If the testing will show no performance degradation - let's have ipsec
non-ipsec path together.
It the testing will show noticeable perfoamce degradation - let's
Have a special rx/tx function for ipsec enabled.
In that case users will still have an option to use ipsec if needed,
and can switch it on/off at runtime.

I think I understand what are you doing here.
You write to the HW register and then poll on that register till HW indicate that the operation completed.
In fact that's not the only place where you have to do same thing.
Let say at dev_rxtx_start():
rxdctl = IXGBE_READ_REG(hw, IXGBE_RXDCTL(rxq->reg_idx));
                rxdctl |= IXGBE_RXDCTL_ENABLE;
                IXGBE_WRITE_REG(hw, IXGBE_RXDCTL(rxq->reg_idx), rxdctl);

                /* Wait until RX Enable ready */
                poll_ms = RTE_IXGBE_REGISTER_POLL_WAIT_10_MS;
                do {
                        rte_delay_ms(1);
                        rxdctl = IXGBE_READ_REG(hw, IXGBE_RXDCTL(rxq->reg_idx));
                } while (--poll_ms && !(rxdctl & IXGBE_RXDCTL_ENABLE));
                if (!poll_ms)
                        PMD_INIT_LOG(ERR, "Could not enable Rx Queue %d",
                                     rx_queue_id);
So my thought was that common macro(inline function will be useful here.
Though I think we have to get rid of implicit parameters.
