net: phy: reset only targeted phy

2015-12-03T20:26:13+00:00

It is possible to address another chip on same MDIO bus. The case is correctly handled for media advertising. It is taken into account only if mii_data->phy_id == phydev->addr. However, this condition was missing for reset case. Signed-off-by: Jérôme Pouiller Signed-off-by: David S. Miller

bnxt_en: Setup uc_list mac filters after resetting the chip.

2015-12-03T20:07:13+00:00

Call bnxt_cfg_rx_mode() in bnxt_init_chip() to setup uc_list and mc_list mac address filters. Before the patch, uc_list is not setup again after chip reset (such as ethtool ring size change) and macvlans don't work any more after that. Modify bnxt_cfg_rx_mode() to return error codes appropriately so that the init chip sequence can detect any failures. Signed-off-by: Michael Chan Signed-off-by: David S. Miller

bnxt_en: enforce proper storing of MAC address

2015-12-03T20:07:13+00:00

For PF, the bp->pf.mac_addr always holds the permanent MAC addr assigned by the HW. For VF, the bp->vf.mac_addr always holds the administrator assigned VF MAC addr. The random generated VF MAC addr should never get stored to bp->vf.mac_addr. This way, when the VF wants to change the MAC address, we can tell if the adminstrator has already set it and disallow the VF from changing it. v2: Fix compile error if CONFIG_BNXT_SRIOV is not set.

bnxt_en: Fixed incorrect implementation of ndo_set_mac_address

2015-12-03T20:07:13+00:00

The existing ndo_set_mac_address only copies the new MAC addr and didn't set the new MAC addr to the HW. The correct way is to delete the existing default MAC filter from HW and add the new one. Because of RFS filters are also dependent on the default mac filter l2 context, the driver must go thru close_nic() to delete the default MAC and RFS filters, then open_nic() to set the default MAC address to HW.

net: lpc_eth: remove irq > NR_IRQS check from probe()

2015-12-03T20:02:24+00:00

If the driver is used on an ARM platform with SPARSE_IRQ defined, semantics of NR_IRQS is different (minimal value of virtual irqs) and by default it is set to 16, see arch/arm/include/asm/irq.h. This value may be less than the actual number of virtual irqs, which may break the driver initialization. The check removal allows to use the driver on such a platform, and, if irq controller driver works correctly, the check is not needed on legacy platforms. Fixes a runtime problem: lpc-eth 31060000.ethernet: error getting resources. lpc_eth: lpc-eth: not found (-6). Signed-off-by: Vladimir Zapolskiy Signed-off-by: David S. Miller

net: mvneta: enable setting custom TX IP checksum limit

2015-12-03T04:35:05+00:00

Since Armada 38x SoC can support IP checksum for jumbo frames only on a single port, it means that this feature should be enabled per-port, rather than for the whole SoC. This patch enables setting custom TX IP checksum limit by adding new optional property to the mvneta device tree node. If not used, by default 1600B is set for "marvell,armada-370-neta" and 9800B for other strings, which ensures backward compatibility. Binding documentation is updated accordingly.

net: mvneta: fix error path for building skb

2015-12-03T04:35:05+00:00

In the actual RX processing, there is same error path for both descriptor ring refilling and building skb fails. This is not correct, because after successful refill, the ring is already updated with newly allocated buffer. Then, in case of build_skb() fail, hitherto code left the original buffer unmapped. This patch fixes above situation by swapping error check of skb build with DMA-unmap of original buffer.

net: mvneta: fix bit assignment for RX packet irq enable

2015-12-03T04:35:05+00:00

A value originally defined in the driver was inappropriate. Even though the ingress was somehow working, writing MVNETA_RXQ_INTR_ENABLE_ALL_MASK to MVNETA_INTR_ENABLE didn't make any effect, because the bits [31:16] are reserved and read-only. This commit updates MVNETA_RXQ_INTR_ENABLE_ALL_MASK to be compliant with the controller's documentation.
