Bug Fix(es): * Backport TCP follow-up for small buffers (BZ#1739184) * TCP performance regression after CVE-2019-11478 bug fix (BZ#1743170) * RHEL8.0 - bnx2x link down, caused by transmit timeouts during load test (Marvell/Cavium/QLogic) (L3:) (BZ#1743548) * block: blk-mq improvement (BZ#1780567) * RHEL8.0 - Regression to RHEL7.6 by changing force_latency found during RHEL8.0 validation for SAP HANA on POWER (BZ#1781111) * blk-mq: overwirte performance drops on real MQ device (BZ#1782183) * RHEL8: creating vport takes lot of memory i.e 2GB per vport which leads to drain out system memory quickly. (BZ#1782705) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.
