Removed Items
-------------
* **Disabled building all the Linux kernel modules by default.**
- In order to remove the build time dependency with Linux kernel,
+ In order to remove the build time dependency on the Linux kernel,
the Technical Board decided to disable all the kernel modules
by default from 20.02 version.
The internal tail write coalescing feature was removed as not compatible with
dual-thread feature. It was replaced with a threshold feature. At busy times
if only a small number of packets can be enqueued, each enqueue causes
- an expensive MMIO write. These MMIO write occurrences can be optimised by using
- the new threshold parameter on process start. Please see qat documentation for
+ an expensive MMIO write. These MMIO write occurrences can be optimized by using
