2024-02-01GP-2221 Prevent receive errors on wwan0 when MTU is less than 1500Serhii Kostiuk2
Changing the MTU for wwan affects the "rx_urb_size" value. When "rx_urb_size" (effectively an MRU) is too low, the host rejects packets from the radio, causing a packet loss, connection issues, increasing interface error counters, and (potentially) high load on the host CPU to the point when the host effectively stops responding to user input (reproduced on MTCDT-L4E1 with Atmel). Decouple MTU and "MRU" by setting "rx_usb_size" to a relatively high value that is different from MTU. NOTE: The target kernel in 6.3.x is linux-at91_5.4.199 as of the time of writing. Assumptions: - Cellular networks never send packets bigger than 1500 bytes; - the radio may send a packet bigger than the MTU size reported in wds-get-current-settings; - mLinux and mPower do not use packet aggreggation (like qmap), hence no need in MTU/MRU sizes bigger than 1500.
2024-02-01Atmel: Remove nftables from mLinux 6.3.x and mPower 6.3.xSerhii Kostiuk2
nftables is only for the future versions of the firmware, the 6.3.x branch shall keep using iptables. Revert "Merge branch 'md/nftables' into '6'" This reverts commit 8b53cf652131da6537871492dcb7a3cb055a72cb, reversing changes made to b9d90d071db617bd845293612f41fcb1059f5911.
