2019-11-04net: of_get_phy_mode: Change API to solve int/unit warningsAndrew Lunn
Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error. Add error checks to all users of of_get_phy_mode() Fixup a few reverse christmas tree errors Fixup a few slightly malformed reverse christmas trees v3: Fix 0-day reported errors.

Couple conflicts resolved here: 1) In the MACB driver, a bug fix to properly initialize the RX tail pointer properly overlapped with some changes to support variable sized rings. 2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix overlapping with a reorganization of the driver to support ACPI, OF, as well as PCI variants of the chip. 3) In 'net' we had several probe error path bug fixes to the stmmac driver, meanwhile a lot of this code was cleaned up and reorganized in 'net-next'. 4) The cls_flower classifier obtained a helper function in 'net-next' called __fl_delete() and this overlapped with Daniel Borkamann's bug fix to use RCU for object destruction in 'net'. It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net>
2016-12-02net: ethernet: altera: TSE: do not use tx queue lock in tx completion handlerLino Sanfilippo
The driver already uses its private lock for synchronization between xmit and xmit completion handler making the additional use of the xmit_lock unnecessary. Furthermore the driver does not set NETIF_F_LLTX resulting in xmit to be called with the xmit_lock held and then taking the private lock while xmit completion handler does the reverse, first take the private lock, then the xmit_lock. Fix these issues by not taking the xmit_lock in the tx completion handler. Signed-off-by: Lino Sanfilippo <LinoSanfilippo@gmx.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-12-02net: ethernet: altera_tse: add support for SGMII PCSNeill Whillans
Add support for the (optional) SGMII PCS functionality of the Altera TSE MAC. If the phy-mode is set to 'sgmii' then we attempt to discover and initialise the PCS so that the MAC can communicate to the PHY. The PCS IP block provides a scratch register for testing presence of the PCS, which is mapped into one of the two MDIO spaces present in the MAC's register space. Once we have determined that the scratch register is functioning, we attempt to initialise the PCS to auto-negotiate an SGMII link with the PHY. There is no need to monitor or manage the SGMII link beyond this, since the normal PHY MDIO will then be used to monitor the media layer. The Altera TSE MAC has only one way in which it can be configured with an SGMII PCS, and as such, this patch only looks to the phy-mode to select whether or not to attempt to initialise the PCS registers. During initialisation, we report the PCS's equivalent of a PHY ID register. This can be parameterised during the IP instantiation and is often left as '0x00000000' which is not an error.

(incl. custom patches for SGMII-PCS). According to the datasheet if ff_tx_err (avalon-streaming) is set it is forwarded to gm_tx_err.

The xfrm6_output.c has a bug fix which overlaps the renaming of skb->local_df to skb->ignore_df. In the Altera TSE driver cases, the register access cleanups in net-next overlapped with bug fixes done in net. Similarly a bug fix to send ALB packets in the bonding driver using the right source address overlaps with cleanups in net-next. Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-15Altera TSE: Disable Multicast filtering to workaround problemVince Bridgers
This patch disables multicast hash filtering if present in the hardware and uses promiscuous mode instead until the problem with multicast filtering has been debugged, integrated and tested. Signed-off-by: Vince Bridgers <vbridgers2013@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-05-15Altera TSE: Fix sparse errors and warningsVince Bridgers
This patch fixes the many sparse errors and warnings contained in the initial submission of the Altera Triple Speed Ethernet driver, and a few minor cppcheck warnings. Changes are tested on ARM and NIOS2 example designs, and compile tested against multiple architectures. Typical issues addressed were as follows: altera_tse_ethtool.c:136:19: warning: incorrect type in argument 1 (different address spaces) altera_tse_ethtool.c:136:19: expected void const volatile [noderef] <asn:2>*addr altera_tse_ethtool.c:136:19: got unsigned int *<noident> ... altera_sgdma.c:129:31: warning: cast removes address space of expression Signed-off-by: Vince Bridgers <vbridgers2013@gmail.com> Signed-off-by: David S.

2014-05-13net: get rid of SET_ETHTOOL_OPSWilfried Klaebe
net: get rid of SET_ETHTOOL_OPS Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone. This does that. Mostly done via coccinelle script: @@ struct ethtool_ops *ops; struct net_device *dev; @@ - SET_ETHTOOL_OPS(dev, ops); + dev->ethtool_ops = ops; Compile tested only, but I'd seriously wonder if this broke anything.

Conflicts: drivers/net/ethernet/altera/altera_sgdma.c net/netlink/af_netlink.c net/sched/cls_api.c net/sched/sch_api.c The netlink conflict dealt with moving to netlink_capable() and netlink_ns_capable() in the 'net' tree vs. supporting 'tc' operations in non-init namespaces. These were simple transformations from netlink_capable to netlink_ns_capable. The Altera driver conflict was simply code removal overlapping some void pointer cast cleanups in net-next.
