2020-03-23octeontx2-pf: Cleanup all receive buffers in SG descriptorGeetha sowjanya
With MTU sized receive buffers it is not expected to have CQE_RX with multiple receive buffer pointers. But since same physcial link is shared by PF and it's VFs, the max receive packet configured at link could be morethan MTU. Hence there is a chance of receiving plts morethan MTU which then gets DMA'ed into multiple buffers and notified in a single CQE_RX. This patch treats such pkts as errors and frees up receive buffers pointers back to hardware. Also on the transmit side this patch sets SMQ MAXLEN to max value to avoid HW length errors for the packets whose size > MTU, eg due to path MTU.

2020-03-23octeontx2-vf: Link event notification supportTomasz Duszynski
VF shares physical link with PF. Admin function (AF) sends notification to PF whenever a link change event happens. PF has to forward the same notification to each of the enabled VF. PF traps START/STOP_RX messages sent by VF to AF to keep track of VF's enabled/disabled state.

2020-03-23octeontx2-vf: Virtual function driver supportTomasz Duszynski
On OcteonTx2 silicon there two two types VFs, VFs that share the physical link with their parent SR-IOV PF and the VFs which work in pairs using internal HW loopback channels (LBK). Except for the underlying Rx/Tx channel mapping from netdev functionality perspective they are almost identical. This patch adds netdev driver support for these VFs. Unlike it's parent PF a VF cannot directly communicate with admin function (AF) and it has to go through PF for the same. The mailbox communication with AF works like 'VF <=> PF <=> AF'. Also functionality wise VF and PF are identical, hence to avoid code duplication PF driver's APIs are resued here for HW initialization, packet handling etc etc ie almost everything. For VF driver to compile as module exported few of the existing PF driver APIs.

2020-03-23octeontx2-pf: Handle VF function level resetGeetha sowjanya
When FLR is initiated for a VF (PCI function level reset), the parent PF gets a interrupt. PF then sends a message to admin function (AF), which then cleanups all resources attached to that VF. Also handled IRQs triggered when master enable bit is cleared or set for VFs. This handler just clears the transaction pending ie TRPEND bit.

2020-03-23octeontx2-pf: Enable SRIOV and added VF mbox handlingSunil Goutham
Added 'sriov_configure' to enable/disable virtual functions (VFs). Also added handling of mailbox messages from these VFs. Admin function (AF) is the only one with all priviliges to configure HW, alloc resources etc etc, PFs and it's VFs have to request AF via mbox for all their needs. But unlike PFs, their VFs cannot send a mbox request directly. A VF shares a mailbox region with it's parent PF, so VF sends a mailbox msg to PF and then PF forwards it to AF. Then AF after processing sends response to PF which it again forwards to VF. This patch adds support for this 'VF <=> PF <=> AF' mailbox communication.

2020-03-21soc: qcom: ipa: kill IPA_RX_BUFFER_ORDERAlex Elder
Don't assume the receive buffer size is a power-of-2 number of pages. Instead, define the receive buffer size independently, and then compute the page order from that size when needed. This fixes a build problem that arises when the ARM64_PAGE_SHIFT config option is set to have a page size greater than 4KB. The problem was identified by Linux Kernel Functional Testing. The IPA code basically assumed the page size to be 4KB. A larger page size caused the receive buffer size to become correspondingly larger (32KB or 128KB for ARM64_16K_PAGES and ARM64_64K_PAGES, respectively). The receive buffer size is used to compute an "aggregation byte limit" value that gets programmed into the hardware, and the large page sizes caused that limit value to be too big to fit in a 5 bit field. This triggered a BUILD_BUG_ON() call in ipa_endpoint_validate_build(). This fix causes a lot of receive buffer memory to be wasted if system is configured for page size greater than 4KB. But such a misguided configuration will now build successfully.

2020-03-20net: dsa: sja1105: Add support for the SGMII portVladimir Oltean
SJA1105 switches R and S have one SerDes port with an 802.3z quasi-compatible PCS, hardwired on port 4. The other ports are still MII/RMII/RGMII. The PCS performs rate adaptation to lower link speeds; the MAC on this port is hardwired at gigabit. Only full duplex is supported. The SGMII port can be configured as part of the static config tables, as well as through a dedicated SPI address region for its pseudo-clause-22 registers. However it looks like the static configuration is not able to change some out-of-reset values (like the value of MII_BMCR), so at the end of the day, having code for it is utterly pointless. We are just going to use the pseudo-C22 interface. Because the PCS gets reset when the switch resets, we have to add even more restoration logic to sja1105_static_config_reload, otherwise the SGMII port breaks after operations such as enabling PTP timestamping which require a switch reset. >From PHYLINK perspective, the switch supports *only* SGMII (it doesn't support 1000Base-X). It also doesn't expose access to the raw config word for in-band AN in registers MII_ADV/MII_LPA. It is able to work in the following modes: - Forced speed - SGMII in-band AN slave (speed received from PHY) - SGMII in-band AN master (acting as a PHY) The latter mode is not supported by this patch. It is even unclear to me how that would be described. There is some code for it left in the patch, but 'an_master' is always passed as false.

2020-03-19net: phy: mscc: add missing check on a phy_write return valueAntoine Tenart
Commit a5afc1678044 ("net: phy: mscc: add support for VSC8584 PHY") introduced a call to 'phy_write' storing its return value to a variable called 'ret'. But 'ret' never was checked for a possible error being returned, and hence was not used at all. Fix this by checking the return value and exiting the function if an error was returned. As this does not fix a known bug, this commit is mostly cosmetic and not sent as a fix. Signed-off-by: Antoine Tenart <antoine.tenart@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
