(CVE-2019-0154)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.

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)
