* net: hns: bug fix about TSO on|off when there is trafficDaode Huang2016-06-211-4/+4
| | | | | | | | | | | When enable/disable tso, the driver tries to access the hardware register, but this operation will cause the port unavalible when there is traffic. This patch tries to enable TSO when initialize, then control tso through TSE bit in transmit descriptor.

* net: hns: fix bug that alloc skb fail lead to port unavailableJun He2016-06-211-2/+3
| | | | | | | | | | | | | | When hns_nic_poll_rx_skb alloc skb fail, it will break receive cycle and read new fbd_num to start new receive cycle. It recomputes cycle num is fbd_num minus clean_count, actually this cycle num is too big because it drop out receive cycle. It brings about the port unavailable. So we will goto out when alloc skb fail to fix this bug.

* net: hns: bug fix about led control logic when link downDaode Huang2016-06-211-5/+7
| | | | | | | | | | | | | The default driver sets anchor led bit to 0 when link down, actually, the anchor bit should be set to 1, so fixes it when link status is down. Secondly, change the return value of cpld_set_led_id to 0, which means leave the cpld to control led blink frequece other than the driver itself.

* net: hns: fix the wrong speed for bondQianqian Xie2016-06-212-20/+25
| | | | | | | | | | | | | | | For debug-ports,there are two non-synchronized processes: Speed-Auto-Negotiation and Link-Update-Status. The two processes are towed by two different state machines. Bond reads the speed when link up, but the speed maybe not update the right value at that time.That make for bond's wrong speed. Thus only one state machine should be used and if phy_state_machine is used, it does not need to do hns_nic_update_link_status().

* net: hns: fix ethtool loopback fail bugKejian Yan2016-06-211-21/+14Star
| | | | | | | | | | | | | | | | | | When run ethtool cmd(ethtool -t ethx) again and again for a long time, it will be probabilistically fail. The PHYs' registers may be on different pages, so it must be switch to the right page before setting PHYs' registers. And __lb_up() calls phy_start() to startup the PHYs device, but this function may change Copper Control Register(Page 0, Register 0) to an other value. It would cause phy loopback test fail. if we remove phy_start(), we have to remove the relative phy_stop(), phy_disconnect() when doing phy loopback to keep the phy stay in right status.

* net: hns: set debug port irq index to 0Daode Huang2016-04-262-11/+2Star
| | | | | | | | | | As debug ports are moved from service dsaf to debug dsaf, the interrupts offset should start from 0, So this patch re-defines the offset index of debug ports.

| | | | | | | | | | This patch adds a new dsaf mode named "single-port" mode for debug port. This mode only contains one debug port.

* net: hns: add support of pause frame ctrl for HNS V2Lisheng2016-04-036-38/+104
| | | | | | | | | | | | | | | The patch adds support of pause ctrl for HNS V2, and this feature is lost by HNS V1: 1) service ports can disable rx pause frame, 2) debug ports can open tx/rx pause frame. And this patch updates the REGs about the pause ctrl when updated status function called by upper layer routine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The hilink status reg in HNS V2 is different from HNS v1. In HNS V2, It distinguishes differnt lane status according to the bit-field of the reg. As is shown below: [0:0] ---> lane0 [1:1] ---> lane1 ... But the current driver reads the reg to get the hilink status ONLY concidering HNS V1 situation. Here is a patch to support both of them.
