2016-06-28drivers: net: stmmac: add port selection programmingGiuseppe CAVALLARO8-2/+53
In case of SGMII more, for example when a MAC2MAC connection is needed, the port selection bits (inside the MAC configuration registers) have to be programmed according to the link selected. So the patch adds a new DT parameter to pass the port selection and to programmed related PCS and CORE to use it. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.

2016-06-28drivers: net: stmmac: rework core ISR to better manage PCS and PMTGiuseppe CAVALLARO8-35/+79
By default, all gmac cores disable the PCS block and always enable the PMT. Note that this is done in a different way by 3.x and 4.x cores. With this rework, PCS and PMT interrupt masks can be driven by parameters now moved inside the mac_device_info structure and the settings follow what the HW capability register reports.

2016-06-28drivers: net: stmmac: reworking the PCS code.Giuseppe CAVALLARO9-165/+350
The 3.xx and 4.xx synopsys gmacs have a very similar PCS embedded module and they share almost the same registers: for example: AN_Control, AN_Status, AN_Advertisement, AN_Link_Partner_Ability, AN_Expansion, TBI_Extended_Status. Just the RGMII/SMII Control/Status register differs. So This patch aims to reorganize and enhance the PCS support. It removes the existent support from the dwmac1000/dwmac4_core.c moving basic PCS functions inside a new file called: stmmac_pcs.h. The patch also reviews the available APIs to be better shared among different hardware and easily enhanced to support new features.

2016-06-28of_mdio: select fixed phy support unconditionallyArnd Bergmann3-8/+3
Calling the fixed-phy functions when CONFIG_FIXED_PHY=m as a previous change tried cannot work if the caller is in built-in code: drivers/of/built-in.o: In function `of_phy_register_fixed_link': of_reserved_mem.c:(.text+0x85e0): undefined reference to `fixed_phy_register' Making of_mdio depend on 'FIXED_PHY || !FIXED_PHY' would solve this dependency by enforcing that OF_MDIO itself becomes a loadable module when FIXED_PHY=y, but that creates a different dependency as it breaks any built-in ethernet driver that uses of_mdio. Making FIXED_PHY a bool option also cannot work, since it depends on PHYLIB, which again is tristate. This version now uses 'select FIXED_PHY' to ensure that the fixed-phy portion of of_mdio is not optional. The main downside of this is a small increase in code size for cases that do not need fixed phy support, but it should avoid all of the link-time problems.

When LLDP/DCBX change happens the i40e driver code flow tried to notify the client(s) for each of the PF VSIs. This resulted into kernel panic on the first VSI that didn't have any netdev associated to it.

More importantly, if we tell them that is what we did, we want to actually do it and allow traffic into all of the queues we have allocated.

2016-06-27i40evf: don't overflow bufferMitch Williams1-0/+8
If the user adds an obscene amount of MAC addresses, the driver will run into the situation where it has too many address requests to fit into a single PF message. The driver checks for this case, and calculates the maximum number of messages that it can send. Then it completely ignores this count and overflows the buffer. Fix this by checking the address count and bailing out of the loop at the appropriate time.

2016-06-27phy: improve safety of fixed-phy MII register readingRussell King1-7/+21
There is no prevention of a concurrent call to both fixed_mdio_read() and fixed_phy_update_state(), which can result in the state being modified while it's being inspected. Fix this by using a seqcount to detect modifications, and memcpy()ing the state.

If the burst seizes for "moderation period" time then an interrupt will be issued immediately. CQE based moderation is off by default and can be controlled via ethtool set_priv_flags.

2016-06-27be2net: Fix broadcast echoes from EVB in BE3Somnath Kotur2-1/+33
On SR-IOV profiles, when the user connects a Linux Bridge or OVS to a BE3 vport, they suffer the "broadcast/multicast echo" problem. BE3 EVB echoes broadcast and multicast packets back to PF's vport confusing the Linux bridge. BE3 relies on the src-mac addr being programmed on the interface to avoid sending back an echo of a broadcast or multicast packet on a vPort. When a Linux bridge is connected to a BE3, the mac-addr of the VM behind the bridge doesn't get configured on the vPort and so echo cancellation doesn't work. This patch worksaround this problem by disabling the EVB initially and re-enabling it *only* when SR-IOV is enabled by the user. For the driver fix to work, the BE3 FW version must be >= 11.1.84.0.

2016-06-27be2net: support asymmetric rx/tx queue countsSathya Perla3-25/+74
be2net so far supported creation of RX/TX queues only in pairs. On configs where rx and tx queue counts are different, creation of only the lesser number of queues has been supported. This patch now allows a combination of RX/TX-only channels along with combined channels. N TX-queues and M RX-queues can be created with the following cmds: ethtool -L ethX combined N rx M-N (when N < M) ethtool -L ethX combined M tx N-M (when M < N) Setting both RX-only and TX-only channels is still not supported. It is mandatory to create atleast one combined channel. Signed-off-by: Sathya Perla <sathya.perla@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-27be2net: fix definition of be_max_eqs()Sathya Perla2-18/+19
The EQs available on a function are shared between NIC and RoCE. The be_max_eqs() macro was so far being used to refer to the max number of EQs available for NIC. This has caused some confusion in the code. To fix this confusion this patch introduces a new macro called be_max_nic_eqs() to refer to the max number of EQs avialable for NIC only and renames be_max_eqs() to be_max_func_eqs().

2016-06-27net: fec: use a more proper compatible string for i.MX6UL type deviceFugang Duan1-0/+8
i.MX6UL is a member in i.MX series family, the SOC FEC inherits from i.MX6SX but removes some IP features, lets define a new type for fec device. Signed-off-by: Fugang Duan <fugang.duan@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-27net: fec: add interrupt coalesc quirk flagFugang Duan2-10/+11
Different i.MX SOC FEC support different features like : - i.MX6Q/DL FEC does not support AVB and interrupt coalesc - i.MX6SX/i.MX7D supports AVB and interrupt coalesc - i.MX6UL/ULL does not support AVB, but support interrupt coalesc So, add new quirk flag to judge the supported features.

Add constants and callback functions for the dwmac on rk3228/rk3229 socs. As can be seen, the base structure is the same, only registers and the bits in them moved slightly.
