+Subject: [PATCH 1/3] ice: reduce TX scheduler default burst size to 2 KB
+
+Reduce ICE_SCHED_DFLT_BURST_SIZE from 15 KB to 2 KB to meet
+ST 2110-21 narrow-sender compliance requirements.
+
+The E810 TX scheduler uses a token bucket algorithm for
+hardware rate limiting. A 15 KB burst allows ~10 max-size
+Ethernet frames to be sent back-to-back, creating
+micro-bursts that violate the ST 2110-21 narrow-sender VRX
+budget. Reducing to 2 KB (~1.3 frames) forces near-constant
+rate output matching the configured shaper profile, keeping
+inter-packet spacing within the required jitter tolerance.
+
+This must match the DPDK PMD-side burst size for consistent
+PF/VF rate limiting behavior.

+Subject: [PATCH 2/3] ice: allow VIRTCHNL_VF_LARGE_NUM_QPAIRS with ICE_LUT_VSI
+
+Remove the rss_lut_type != ICE_LUT_VSI restriction when
+negotiating the VIRTCHNL_VF_LARGE_NUM_QPAIRS capability.
+
+ST2110 workloads create one TX/RX queue pair per media
+session. A single VF handling multiple simultaneous video,
+audio, and ancillary data sessions can easily exceed the
+default 16 queue pair limit. LARGE_NUM_QPAIRS lifts this cap
+but was blocked when using ICE_LUT_VSI RSS lookup type.
+
+For ST2110 use cases, RSS distribution is not the primary
+concern since media streams use flow director rules for
+steering. The LUT type restriction unnecessarily prevents
+allocating enough queues for multi-session operation.

+Subject: [PATCH 3/3] virtchnl: fix MAP_QUEUE_VECTOR legacy size calculation
+
+VF traffic could be fully blocked when processing
+VIRTCHNL_OP_MAP_QUEUE_VECTOR (opcode 111) due to an ABI length
+mismatch between PF validation and VF message size computation.
+
+The queue-vector map payload uses a legacy [1]-tail struct size
+convention. Using __vss_full() over-counts one element for this
+struct, making PF expect a message 16 bytes larger than what VF
+sends for a given map count.
+
+For 32 maps:
+- VF sends: 8 + 32*16 = 520
+- PF expected (wrong): 24 + 32*16 = 536
+- PF expected (correct): 24 + (32-1)*16 = 520
+
+This mismatch causes PF to reject opcode 111 with -EINVAL /
+VIRTCHNL_STATUS_ERR_PARAM. As a result, queue->vector mapping is not
+established, RX queues are never polled by NAPI, and VF software sees
+zero packets despite hardware RX counters increasing.
+
+Fix by switching virtchnl_ss_queue_vector_maps() from __vss_full()
+to __vss_byelem(), which is the correct helper for legacy structs
+whose LEGACY_SIZEOF already includes one element.
