Rather than construct special phy device addresses to access C45 registers, use the mmd helpers. These will directly call the C45 API of the MDIO bus driver. Signed-off-by:

VxLAN belongs to UDP-based encapsulation protocol. Inner TSO for VxLAN packet with udpcsum requires offloading of outer header csum. The device doesn't support outer header csum offload. However, inner TSO for VxLAN with udpcsum can still work with GSO_PARTIAL offload, which means outer udp csum computed by stack and inner tcp segmentation finished by hardware. Thus, the patch enable features "NETIF_F_GSO_UDP_TUNNEL_CSUM" and "NETIF_F_GSO_PARTIAL" and set gso_partial_features. Signed-off-by:

Since o_seqno is now atomic_t, we can always turn on NETIF_F_LLTX for [IP6]GRE[TAP] devices, since we no longer need the TX lock (&txq->_xmit_lock). We could probably do the same thing to [IP6]ERSPAN devices as well, but I'm not familiar with them yet. For example, ERSPAN devices are initialized as |= GRE_FEATURES in erspan_tunnel_init(), but I don't see IP6ERSPAN devices being initialized as |= GRE6_FEATURES. Where should we initialize IP6ERSPAN devices' ->features? Please suggest if I'm missing something, thanks!

Alexandru Tachici says: ==================== net: phy: adin1100: Add initial support for ADIN1100 industrial PHY The ADIN1100 is a low power single port 10BASE-T1L transceiver designed for industrial Ethernet applications and is compliant with the IEEE 802.3cg Ethernet standard for long reach 10 Mb/s Single Pair Ethernet. The ADIN1100 uses Auto-Negotiation capability in accordance with IEEE 802.3 Clause 98, providing a mechanism for exchanging information between PHYs to allow link partners to agree to a common mode of operation. The concluded operating mode is the transmit amplitude mode and master/slave preference common across the two devices. Both device and LP advertise their ability and request for increased transmit at: - BASE-T1 autonegotiation advertisement register [47:32]\ Clause 45.2.7.21 of Standard 802.3 - BIT(13) - 10BASE-T1L High Level Transmit Operating Mode Ability - BIT(12) - 10BASE-T1L High Level Transmit Operating Mode Request For 2.4 Vpp (high level transmit) operation, both devices need to have the High Level Transmit Operating Mode Ability bit set, and only one of them needs to have the High Level Transmit Operating Mode Request bit set. Otherwise 1.0 Vpp transmit level will be used.

Add basic support for ADIN1100. Alexandru Ardelean (1): net: phy: adin1100: Add initial support for ADIN1100 industrial PHY 1. Added 10baset-T1L link modes. 2. Added 10-BasetT1L registers. 3. Added Base-T1 auto-negotiation registers. For Base-T1 these registers decide master/slave status and TX voltage of the device and link partner. 4. Added 10BASE-T1L support in phy-c45.c. Now genphy functions will call Base-T1 functions where registers don't match, like the auto-negotiation ones. 5. Convert MSE to SQI using a predefined table and allow user access through ethtool. 6.

Add a tristate property to advertise desired transmit level. If the device supports the 2.4 Vpp operating mode for 10BASE-T1L, as defined in 802.3gc, and the 2.4 Vpp transmit voltage operation is desired, property should be set to 1. This property is used to select whether Auto-Negotiation advertises a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to 1, the PHY shall advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode. If property is set to zero, the PHY shall not advertise a request to operate the 10BASE-T1L PHY in increased transmit level mode. Reviewed-by:

This patch is needed because the BASE-T1 uses different registers for status, control and advertisement to those already employed in the existing phy-c45 functions. Where required, genphy_c45 functions will now check whether the device supports BASE-T1 and use the specific registers instead: 45.2.7.19 BASE-T1 AN control register, 45.2.7.20 BASE-T1 AN status, 45.2.7.21 BASE-T1 AN advertisement register, 45.2.7.22 BASE-T1 AN LP Base Page ability register, 45.2.1.185 BASE-T1 PMA/PMD control register.

Pavel Begunkov says: ==================== UDP sock_wfree optimisations The series is not UDP specific but that the main beneficiary. 2/3 saves one atomic in sock_wfree() and on top 3/3 removes an extra barrier. Tested with UDP over dummy netdev, 2038491 -> 2099071 req/s (or around +3%). note: in regards to 1/3, there is a "Should agree with poll..." comment that I don't completely get, and there is no git history to explain it. Though I can't see how it could rely on having the second check without racing with tasks woken by wake_up*().

Now we have a separate path for sock_def_write_space() and can go one step further. When it's called from sock_wfree() we know that there is a preceding atomic for putting down ->sk_wmem_alloc. We can use it to replace to replace smb_mb() with a less expensive smp_mb__after_atomic(). It also removes an extra RCU read lock/unlock as a small bonus. Signed-off-by:

Pavel Begunkov authored
For non SOCK_USE_WRITE_QUEUE sockets, sock_wfree() (atomically) puts ->sk_wmem_alloc twice. It's needed to keep the socket alive while calling ->sk_write_space() after the first put. However, some sockets, such as UDP, are freed by RCU (i.e. SOCK_RCU_FREE) and use already RCU-safe sock_def_write_space(). Carve a fast path for such sockets, put down all refs in one go before calling sock_def_write_space() but guard the socket from being freed by an RCU read section. note: because TCP sockets are marked with SOCK_USE_WRITE_QUEUE it doesn't add extra checks in its path.

Except for minor rounding differences the first ->sk_wmem_alloc test in sock_def_write_space() is a hand coded version of sock_writeable(). Replace it with the helper, and also kill the following if duplicating the check. Signed-off-by:

Robert Hancock authored
With some SFP modules, such as Finisar FCLF8522P2BTL, the PHY hardware strapping defaults to 1000BaseX mode, but the kernel prefers to set them for SGMII mode. When this happens and the PHY is soft reset, the BMSR status register is updated, but this happens after the kernel has already read the PHY abilities during probing. This results in support not being detected for, and the PHY not advertising support for, 10 and 100 Mbps modes, preventing the link from working with a non-gigabit link partner. When the PHY is being configured for SGMII mode, call genphy_read_abilities again in order to re-read the capabilities, and update the advertising field accordingly. Signed-off-by:
