This patch adds logic to reconfigure the comphy/GoP/MAC when the link state is updated at runtime. This is very useful on boards where many link speed are supported: depending on what is negotiated the PPv2 driver will automatically reconfigures the link between the PHY and the MAC.

When the link status changes, the phylib calls the link_event function in the mvpp2 driver. Before this patch only the egress/ingress transmit was enabled/disabled. This patch adds more functionality to the link status management code by enabling/disabling the port per-cpu interrupts, and the port itself. The queues are now stopped as well, and the netif carrier helpers are called. Signed-off-by: NAntoine Tenart <antoine.tenart@free-electrons.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

On some platforms, the comphy is between the MAC GoP and the PHYs. The mvpp2 driver currently relies on the firmware/bootloader to configure the comphy. As a comphy driver was added to the generic PHY framework, this patch uses it in the mvpp2 driver to configure the comphy at boot time to avoid relying on the bootloader.

On the CP110 unit, which can be found on various Marvell platforms such as the 7k and 8k (currently), a comphy (common PHYs) hardware block can be found. This block provides a number of PHYs which can be used in various modes by other controllers (network, SATA ...). These common PHYs must be configured for the controllers using them to work correctly either at boot time, or when the system runs to switch the mode used. This patch adds a driver for this comphy hardware block, providing callbacks for the its PHYs so that consumers can configure the modes used. As of this commit, two modes are supported by the comphy driver: sgmii and 10gkr.

When moving the IRDA code out of net/ into drivers/staging/irda/net, the link order changes when IRDA is built into the kernel. That causes a kernel crash at boot time as netfilter isn't initialized yet. To fix this, move the init call level of the irda core to be device_initcall() as the link order keeps this being initialized at the correct time.

There is a difference in the bit position of the normal interrupt summary enable (NIE) and abnormal interrupt summary enable (AIE) between revisions of the hardware. For older revisions the NIE and AIE bits are positions 16 and 15 respectively. For newer revisions the NIE and AIE bits are positions 15 and 14. The effect in changing the bit position is that newer hardware won't receive AIE interrupts in the current version of the driver. Specifically, the driver uses this interrupt to collect statistics on when a receive buffer unavailable event occurs and to restart the driver/device when a fatal bus error occurs. Update the driver to set the interrupt enable bit based on the reported version of the hardware. Signed-off-by: NTom Lendacky <thomas.lendacky@amd.com> Signed-off-by: NDavid S.

The values are shared between VXLAN-GPE and NSH. Originally probably by coincidence but I notified both working groups about this last year and they seem to keep the values in sync since then. Hopefully they'll get a single IANA registry for the values, too. (I asked them for that.) Factor out the code to be shared by the NSH implementation. NSH and MPLS values are added in this patch, too. For MPLS, the drafts incorrectly assign only a single value, while we have two MPLS ethertypes. I raised the problem with both groups. For now, I assume the value is for unicast. Signed-off-by: NJiri Benc <jbenc@redhat.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

RSB_SWAP0 needs to match the host CPU endian, and it needs to be set for LE and clear for BE. RSB_SWAP1 must always be cleared for SYSTEMPORT Lite. With these settings, we have the Receive Status Block always match the host endian and we do not need to perform any conversion. Since there is not necessarily a CONFIG_CPU_LITTLE_ENDIAN option defined, we test for !CONFIG_CPU_BIG_ENDIAN which is guaranteed to be set.

This patch adds support for offloading TC based flow rules and actions for the 'flower' classifier in the bnxt_en driver. It includes logic to parse flow rules and actions received from the TC subsystem, store them and issue the corresponding hwrm_cfa_flow_alloc/free FW cmds. L2/IPv4/IPv6 flows and drop, redir, vlan push/pop actions are supported in this patch. In this patch the hwrm_cfa_flow_xxx routines are just stubs. The code for these routines is introduced in the next patch for easier review. Also, the code to query the TC/flower action stats will be introduced in a subsequent patch.

When the number of TX rings is changed (e.g. ethtool -L, enabling XDP TX rings, etc), the current code tries to reserve the new number of TX rings before closing and re-opening the NIC. If we are unable to reserve the new TX rings, we abort the operation and keep the current TX rings. The problem is that the firmware will disable the current TX rings even when it cannot reserve the new set of TX rings. We fix it as follows: 1. Instead of reserving the new set of TX rings, just ask the firmware to check if the new set of TX rings is available. There is a flag in the firmware message to do that. If not available, abort and the current TX rings will not be disabled. 2. Do the actual TX ring reservation in the path that opens the NIC. We keep the number of TX rings currently successfully reserved. If the number of TX rings is different than the reserved TX rings, we call firmware and reserve again.
