Merge branch 'r8152-next'

Hayes Wang says:

====================
Adjust the settings about USB_RX_EARLY_AGG

v2:
For patch #1, replace

	u32 ocp_data;
	ocp_data = tp->coalesce / 8;

with

	u32 ocp_data = tp->coalesce / 8;

And replace

	struct net_device *dev = tp->netdev;
	u32 ocp_data;
	ocp_data = (agg_buf_sz - dev->mtu - VLAN_ETH_HLEN - VLAN_HLEN) / 4;

with

	u32 mtu = tp->netdev->mtu;
	u32 ocp_data = (agg_buf_sz - mtu - VLAN_ETH_HLEN - VLAN_HLEN) / 4;

Use *switch* statement to replace the checking of *if*.

v1:
The USB_RX_EARLY_AGG contains timeout and size. Separate them, and
they could be set independently. Then, the ethtool could be used to
change the timeout according to situation of the platform.
