Pull networking fixes from Jakub Kicinski: "Including fixes from wireless. The ath12k fix to avoid FW crashes requires adding support for a number of new FW commands so it's quite large in terms of LoC. The rest is relatively small. Current release - fix to a fix: - ptp: fix breakage after ptp_vclock_in_use() rework Current release - regressions: - openvswitch: allocate struct ovs_pcpu_storage dynamically, static allocation may exhaust module loader limit on smaller systems Previous releases - regressions: - tcp: fix tcp_packet_delayed() for peers with no selective ACK support Previous releases - always broken: - wifi: ath12k: don't activate more links than firmware supports - tcp: make sure sockets open via passive TFO have valid NAPI ID - eth: bnxt_en: update MRU and RSS table of RSS contexts on queue reset, prevent Rx queues from silently hanging after queue reset - NFC: uart: set tty->disc_data only in success path" * tag 'net-6.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net: (59 commits) net: airoha: Differentiate hwfd buffer size for QDMA0 and QDMA1 net: airoha: Compute number of descriptors according to reserved memory size tools: ynl: fix mixing ops and notifications on one socket net: atm: fix /proc/net/atm/lec handling net: atm: add lec_mutex mlxbf_gige: return EPROBE_DEFER if PHY IRQ is not available net: airoha: Always check return value from airoha_ppe_foe_get_entry() NFC: nci: uart: Set tty->disc_data only in success path calipso: Fix null-ptr-deref in calipso_req_{set,del}attr().
