2021-04-12bnxt_en: Invalidate health register mapping at the end of probe.Vasundhara Volam1-0/+1
After probe is successful, interface may not be bought up in all the cases and health register mapping could be invalid if firmware undergoes reset. Fix it by invalidating the health register at the end of probe. It will be remapped during ifup. Fixes: 43a440c4007b ("bnxt_en: Improve the status_reliable flag in bp->fw_health.")

2021-04-12net: hns3: Fix potential null pointer defererence of null ae_devColin Ian King1-4/+4
The reset_prepare and reset_done calls have a null pointer check on ae_dev however ae_dev is being dereferenced via the call to ns3_is_phys_func with the ae->pdev argument. Fix this by performing a null pointer check on ae_dev and hence short-circuiting the dereference to ae_dev on the call to ns3_is_phys_func.

2021-04-11net: ipa: add IPA v4.5 configuration dataAlex Elder5-4/+447
Add support for the SDX55 SoC, which includes IPA version 4.5. Starting with IPA v4.5, a few of the memory regions have a different number of "canary" values; update comments in the where the region identifers are defined to accurately reflect that. I'll note three differences in SDX55 versus the other two existing platforms (SDM845 and SC7180): - SDX55 uses a 32-bit Linux kernel - SDX55 has four interconnects rather than three - SDX55 uses IPA v4.5, which uses inline checksum offload Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-11net: ipa: disable checksum offload for IPA v4.5+Alex Elder1-0/+16
Checksum offload for IPA v4.5+ is implemented differently, using "inline" offload (which uses a common header format for both upload and download offload). The IPA hardware must be programmed to enable MAP checksum offload, but the RMNet driver is responsible for interpreting checksum metadata supplied with messages. Currently, the RMNet driver does not support inline checksum offload. This support is imminent, but until it is available, do not allow newer versions of IPA to specify checksum offload for endpoints. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

2021-04-11veth: refine napi usagePaolo Abeni1-1/+22
After the previous patch, when enabling GRO, locally generated TCP traffic experiences some measurable overhead, as it traverses the GRO engine without any chance of aggregation. This change refine the NAPI receive path admission test, to avoid unnecessary GRO overhead in most scenarios, when GRO is enabled on a veth peer. Only skbs that are eligible for aggregation enter the GRO layer, the others will go through the traditional receive path. Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-11veth: allow enabling NAPI even without XDPPaolo Abeni1-13/+116
Currently the veth device has the GRO feature bit set, even if no GRO aggregation is possible with the default configuration, as the veth device does not hook into the GRO engine. Flipping the GRO feature bit from user-space is a no-op, unless XDP is enabled. In such scenario GRO could actually take place, but TSO is forced to off on the peer device. This change allow user-space to really control the GRO feature, with no need for an XDP program. The GRO feature bit is now cleared by default - so that there are no user-visible behavior changes with the default configuration. When the GRO bit is set, the per-queue NAPI instances are initialized and registered. On xmit, when napi instances are available, we try to use them. Some additional checks are in place to ensure we initialize/delete NAPIs only when needed in case of overlapping XDP and GRO configuration changes.

2021-04-11veth: use skb_orphan_partial instead of skb_orphanPaolo Abeni1-1/+1
As described by commit 9c4c325252c5 ("skbuff: preserve sock reference when scrubbing the skb."), orphaning a skb in the TX path will cause OoO. Let's use skb_orphan_partial() instead of skb_orphan(), so that we keep the sk around for queue's selection sake and we still avoid the problem fixed with commit 4bf9ffa0fb57 ("veth: Orphan skb before GRO") Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-11phy: sfp: add netlink SFP support to generic SFP codeAndrew Lunn3-0/+48
The new netlink API for reading SFP data requires a new op to be implemented. The idea of the new netlink SFP code is that userspace is responsible to parsing the EEPROM data and requesting pages, rather than have the kernel decide what pages are interesting and returning them. This allows greater flexibility for newer formats. Currently the generic SFP code only supports simple SFPs. Allow i2c address 0x50 and 0x51 to be accessed with page and bank must always be 0. This interface will later be extended when for example QSFP support is added.
