Bug Fix(es) and Enhancement(s):
-
"iavf: refactor iavf_clean_rx_irq to support legacy and flex descriptors" broke rx-vlan-offload on rhel-9.7 [rhel-9.8.z] (JIRA:Rocky Linux-169480)
-
[GNR-D] missing interfaces tspll_cfg (JIRA:Rocky Linux-183201)
-
Rocky Linux9.8z KVM guest panicked in vmmouse driver (JIRA:Rocky Linux-186577)
-
Add Epson RX8111 support to Rocky Linux9.9 [rhel-9.8.z] (JIRA:Rocky Linux-212014)
-
RT scheduler livelock: migrate-disabled task at pushable-list head causes repeated RT push/stopper retries, starving a critical RT task (remaining issue after CVE-2026-45919 fix in 94894c9c477e) [rhel-9.8.z] (JIRA:Rocky Linux-256279)
