As mbox polling is done only in process context, it is better to use schedule_timeout() instead of udelay(). Signed-off-by:

During the first suspend the chip would refuse to enter D3. Subsequent suspends worked okay. During resume the chip is commanded into D0. Doing so during initialization fixes the initial suspend. Signed-off-by:

This patch adds support for using phylib and adds the required mdiobus driver stubs. This allows for less code to be present in the driver and removes the PHY status specific timer which is now handled by phylib directly. Signed-off-by:

Instead of a fixed list of buffers, use the buffer pool correctly and keep track of the outstanding buffer indexes using a fixed table. Resolves reported HBUF_ERR's -- failures due to lack of receive buffers. Signed-off-by:

Today, there are no means to know which port of a hardware device a netdev interface uses. struct net_device conatins a field, dev_id, that can be used for that. Use this field to save the port number in ConnectX that is being used by the net device; port numbers are zero based. Signed-off-by:

Currently such notifications are only generated when the device comes up or the address changes. However one use case for these notifications is to enable faster network recovery after a virtual machine migration (by causing switches to relearn their MAC tables). A migration appears to the network stack as a temporary loss of carrier and therefore does not trigger either of the current conditions. Rather than adding carrier up as a trigger (which can cause issues when interfaces a flapping) simply add an interface which the driver can use to explicitly trigger the notification. Signed-off-by:

"phyinfo" can never be null here because we assigned it an address, so I removed both the assert and the second check inside the if statement. I removed the "phyinfo->phy_layer != NULL" check as well because that was asserted earlier. Walter Harms suggested I move the "phyinfo->phy_ref_count++;" outside the if condition for readability, so I have done that. Signed-off-by:

We already dereferenced uaddr towards the start of the function when we checked that "uaddr->sa_family != AF_CAIF". Both the check here and the earlier check were added in bece7b23: "caif: Rewritten socket implementation". Before that patch, we assumed that we recieved a valid pointer for uaddr, and based on that, I have removed this check. Signed-off-by:

netpoll does an interesting work in zap_completion_queue(), but this was before we did skb orphaning before delivering packets to device. It now makes sense to add a test in dev_kfree_skb_irq() to not queue a skb if already orphaned, and to remove netpoll zap_completion_queue() as a bonus. Signed-off-by:

This partially reverts commit 4ec37de8 ("[IA64] Fix build breakage"), since the commit that made it necessary got reverted earlier (see commit 35926ff5, 'Revert "cpusets: randomize node rotor used in cpuset_mem_spread_node()"') Even if we ever re-introduce this, there is no reason to make __node_random be some architecture-specific function.
