Current memory failure code in the debugfs returns -ENOSPC. This is normally used for indicating that there is no space left on the device and is not applicable for memory allocation failures. Replace this with -ENOMEM. Signed-off-by:

==================== pull-request: ieee802154-next 2022-05-01 Miquel Raynal landed two patch series bundled in this pull request. The first series re-works the symbol duration handling to better accommodate the needs of the various phy layers in ieee802154. In the second series Miquel improves th errors handling from drivers up mac802154. THis streamlines the error handling throughout the ieee/mac802154 stack in preparation for sync TX to be introduced for MLME frames. ==================== Link: https://lore.kernel.org/r/20220501194614.1198325-1-stefan@datenfreihafen.orgSigned-off-by:

Commit a2939745 ("rtnetlink: avoid frame size warning in rtnl_newlink()") moved to allocating the largest attribute array of rtnl_newlink() on the heap. Kalle reports the stack has grown above 1k again: net/core/rtnetlink.c:3557:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=] Move more attrs to the heap, wrap them in a struct. Don't bother with linkinfo, it's referenced a lot and we take its size so it's awkward to move, plus it's small (6 elements). Reported-by:

Andrew Lunn says: ==================== Use MMD/C45 helpers MDIO busses can perform two sorts of bus transaction, defined in clause 22 and clause 45 of 802.3. This results in two register addresses spaces. The current driver structure for indicating if C22 or C45 should be used is messy, and many C22 only bus drivers will wrongly interpret a C45 transaction as a C22 transaction. This patchset is a preparation step to cleanup the situation. It converts MDIO bus users to make use of existing _mmd and _c45 helpers to perform accesses to C45 registers. This will later allow C45 and C22 to be kept separate. ==================== Link: https://lore.kernel.org/r/20220430173037.156823-1-andrew@lunn.chSigned-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.

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:
