On macb only (not gem), when a RX queue corruption was detected from
macb_rx(), the RX queue was reset: during this process the RX ring
buffer descriptor was initialized by macb_init_rx_ring() but we forgot
to also set bp->rx_tail to 0.
Indeed, when processing the received frames, bp->rx_tail provides the
macb driver with the index in the RX ring buffer of the next buffer to
process. So when the whole ring buffer is reset we must also reset
bp->rx_tail so the driver is synchronized again with the hardware.
Since macb_init_rx_ring() is called from many locations, currently from
macb_rx() and macb_init_rings(), we'd rather add the "bp->rx_tail = 0;"
line inside macb_init_rx_ring() than add the very same line after each
call of this function.
Without this fix, the rx queue is not reset properly to recover from
queue corruption and connection drop may occur.

The old logic always enabled the TX-delay when the phy-mode was set to
PHY_INTERFACE_MODE_RGMII. There are dedicated phy-modes which tell the
PHY driver to enable the RX and/or TX delays:
- PHY_INTERFACE_MODE_RGMII should disable the RX and TX delay in the
PHY (if required, the MAC should add the delays in this case)
- PHY_INTERFACE_MODE_RGMII_ID should enable RX and TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_TXID should enable the TX delay in the PHY
- PHY_INTERFACE_MODE_RGMII_RXID should enable the RX delay in the PHY
(currently not supported by RTL8211F)
With this patch we enable the TX delay for PHY_INTERFACE_MODE_RGMII_ID
and PHY_INTERFACE_MODE_RGMII_TXID.
Additionally we now explicity disable the TX-delay, which seems to be
enabled automatically after a hard-reset of the PHY (by triggering it's
reset pin) to get a consistent state (as defined by the phy-mode).
This fixes a compatibility problem with some SoCs where the TX-delay was
also added by the MAC. With the TX-delay being applied twice the TX
clock was off and TX traffic was broken or very slow (<10Mbit/s) on
1000Mbit/s links.
