** Changed in: linux-azure (Ubuntu Plucky)
Status: New => Invalid
** Description changed:
SRU Justification
[Impact]
- * Microsoft requested patches to represent packets transmitted after GSO
- processing.
+ * Microsoft requested MANA patches for the following:
+ * Better spread IRQs per cpu
+ * Represent packets transmitted after GSO processing
+ * Allocate MSI-X vectors in PCI dynamically
+ * Support holes in device list reply msg
[Fix]
- * 1 clean cherry-picks from upstream
- * 7399ef984022: "net: mana: Set tx_packets to post gso processing packet
count"
+ * Plucky:
+ * 5 clean cherry-picks from linux-next
+ * abff71a: "net: mana: Set tx_packets to post gso processing packet count"
+ * 0792c36: "PCI/MSI: Export pci_msix_prepare_desc() for dynamic MSI-X
allocations"
+ * aaf2d66: "PCI: hv: Allow dynamic MSI-X vector allocation"
+ * 52e3cfc: "net: mana: explain irq_setup() algorithm"
+ * 453d635: "net: mana: Allow irq_setup() to skip cpus for affinity"
+ * 1 backport from linux-next
+ * 20542d9: "net: mana: Allocate MSI-X vectors dynamically"
+ * Noble:
+ * 5 clean cherry-picks from upstream
+ * e6160dc: "cpumask: add cpumask_weight_andnot()"
+ * add3803: "cpumask: define cleanup function for cpumasks"
+ * fb37331: "net: mana: add a function to spread IRQs per CPUs"
+ * 6b7d4e6: "net: mana: Assigning IRQ affinity on HT cores"
+ * 4d85b5e: "net: mana: Support holes in device list reply msg"
+ * 5 clean cherry-picks from linux-next
+ * abff71a: "net: mana: Set tx_packets to post gso processing packet count"
+ * 0792c36: "PCI/MSI: Export pci_msix_prepare_desc() for dynamic MSI-X

+ * 1 backport from linux-next
+ * 20542d9: "net: mana: Allocate MSI-X vectors dynamically"
[Test Plan]
* Compile tested
+ * Microsoft to test further
[Regression potential]
- * Changes are localized to MANA. Possibly issues if code paths are
- relying on simple packet incrementing rather than post GSO processing.
+ * Changes are largely localized to MANA and Hyper-V, and either already
+ upstream or queued for upstream in the next merge window. Possible
+ regressions could result in unexpected behavior of MANA driver.
