* ravb: make ravb_ptp_interrupt() *void*Sergei Shtylyov2016-04-143-10/+9
| | | | | | | | | | When we have the ISS.CGIS bit set, we already know that gPTP interrupt has happened, so an extra GIS register check at the end of ravb_ptp_interrupt() seems superfluous. We can model the gPTP interrupt handler like all other dedicated interrupt handlers in the driver and make it *void*.

* net: ethernet: stmmac: GMAC4.xx: Fix TX descriptor preparationAlexandre TORGUE2016-04-141-8/+1
| | | | | | | | | | | On GMAC4.xx each descriptor contains 2 buffers of 16KB (each). Initially, those 2 buffers was filled in dwmac4_rd_prepare_tx_desc but it is actually not needed. Indeed, stmmac driver supports frame up to 9000 bytes (jumbo). So only one buffer is needed.

* net: mediatek: do not set the QID field in the TX DMA descriptorsJohn Crispin2016-04-131-2/+1
| | | | | | | | | | | | | | The QID field gets set to the mac id. This made the DMA linked list queue the traffic of each MAC on a different internal queue. However during long term testing we found that this will cause traffic stalls as the multi queue setup requires a more complete initialisation which is not part of the upstream driver yet. This patch removes the code setting the QID field, resulting in all traffic ending up in queue 0 which works without any special setup.

* net: mediatek: fix TX lockingJohn Crispin2016-04-131-10/+10
| | | | | | | | | | | | Inside the TX path there is a lock inside the tx_map function. This is however too late. The patch moves the lock to the start of the xmit function right before the free count check of the DMA ring happens. If we do not do this, the code becomes racy leading to TX stalls and dropped packets. This happens as there are 2 netdevs running on the same physical DMA ring.

| | | | | | | | | | | | | | | | | | | | | ALE APIs expect to receive port masks as input values for arguments port_mask, untag, reg_mcast, unreg_mcast. But there are few places in code where port masks are passed left-shifted by cpsw_priv->host_port, like below: cpsw_ale_add_vlan(priv->ale, priv->data.default_vlan, ALE_ALL_PORTS << priv->host_port, ALE_ALL_PORTS << priv->host_port, 0, 0); and cpsw is still working just because priv->host_port == 0 and has never ever been changed. Hence, fix port_mask parameters in ALE APIs calls and drop "<< priv->host_port" from all places where it's used to shift valid port mask.

| * stmmac: fix adjust link call in case of a switch is attachedGiuseppe CAVALLARO2016-04-061-12/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While initializing the phy, the stmmac driver sets the PHY_IGNORE_INTERRUPT so the PAL won't call the adjust hook that is needed, on some platforms, e.g. STi, to invoke the glue. The patch allows the PAL to poll the stmmac_adjust_link just one time in case of a switch is attached, setting later the PHY_IGNORE_INTERRUPT flag. Moving this kind of logic inside the adjust_link it makes sense to anticipate the check for EEE that will never initialized in this scenario.

| * e1000: Double Tx descriptors needed check for 82544Alexander Duyck2016-04-061-1/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 82544 has code that adds one additional descriptor per data buffer. However we weren't taking that into account when determining the descriptors needed for the next transmit at the end of the xmit_frame path. This change takes that into account by doubling the number of descriptors needed for the 82544 so that we can avoid a potential issue where we could hang the Tx ring by loading frames with xmit_more enabled and then stopping the ring without writing the tail. In addition it adds a few more descriptors to account for some additional workarounds that have been added over time.

| * e1000: Do not overestimate descriptor counts in Tx pre-checkAlexander Duyck2016-04-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code path is capable of grossly overestimating the number of descriptors needed to transmit a new frame. This specifically occurs if the skb contains a number of 4K pages. The issue is that the logic for determining the descriptors needed is ((S) >> (X)) + 1. When X is 12 it means that we were indicating that we required 2 descriptors for each 4K page when we only needed one. This change corrects this by instead adding (1 << (X)) - 1 to the S value instead of adding 1 after the fact. This way we get an accurate descriptor needed count as we are essentially doing a DIV_ROUNDUP().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enables the use of multiple transmit and receive scrqs allowing the ibmvnic driver to take advantage of multiqueue functionality. To achieve this, the driver must implement the process of negotiating the maximum number of queues allowed by the server. Initially, the driver will attempt to login with the maximum number of tx and rx queues supported by the server. If the server fails to allocate the requested number of scrqs, it will return partial success in the login response. In this case, we must reinitiate the login process from the request capabilities stage and attempt to login requesting fewer scrqs.
