* mt76: fix monitor mode crash with sdio driverDeren Wu2022-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | mt7921s driver may receive frames with fragment buffers. If there is a CTS packet received in monitor mode, the payload is 10 bytes only and need 6 bytes header padding after RXD buffer. However, only RXD in the first linear buffer, if we pull buffer size RXD-size+6 bytes with skb_pull(), that would trigger "BUG_ON(skb->len < skb->data_len)" in __skb_pull(). To avoid the nonlinear buffer issue, enlarge the RXD size from 128 to 256 to make sure all MCU operation in linear buffer. [ 52.007562] kernel BUG at include/linux/skbuff.h:2313!

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds RX IRQ coalescing support to the driver. The mcp251xfd chip doesn't support proper hardware based coalescing, so this patch tries to implemented it in software. The RX-FIFO offers a "FIFO not empty" interrupt, which is used if no coalescing is active. With activated RX IRQ coalescing the "FIFO not empty" interrupt is disabled in the RX IRQ handler and the "FIFO half full" or "FIFO full interrupt" (depending on RX max coalesced frames IRQ) is used instead. To avoid RX CAN frame starvation a hrtimer is setup with RX coalesce usecs IRQ,on timer expiration the "FIFO not empty" is enabled again. Support for ethtool configuration is added in the next patch.

Note: GTP-U with no payload offload is not supported yet. ICE COMMS package is required to create a filter as it contains GTP profiles. Changes in iproute2 [1] are required to be able to add GTP netdev and use GTP-specific options (QFI and PDU type).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Checking only protocol ids while searching for correct FVs can lead to a situation, when incorrect FV will be added to the list. Incorrect means that FV has correct protocol id but incorrect offset. Call ice_get_sw_fv_list with ice_prot_lkup_ext struct which contains all protocol ids with offsets. With this modification allocating and collecting protocol ids list is not longer needed.

| * gtp: Implement GTP echo requestWojciech Drewek2022-03-112-37/+269
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding GTP device through ip link creates the situation where GTP instance is not able to send GTP echo requests. Echo requests are used to check if GTP peer is still alive. With this patch, gtp_genl_ops are extended by new cmd (GTP_CMD_ECHOREQ) which allows to send echo request in the given version of GTP protocol (v0 or v1), from the given ms address to he given peer. TID is not inclued because in all path management messages it should be equal to 0. When GTP echo response is detected, multicast message is send to everyone in the gtp_genl_family. Message contains GTP version, ms address and peer address.
