New Release: Linux Kernel 5.5

Linux kernel 5.5 (available here) has been released. Here are the highlights from a Linux on Z perspective:
  • OSA Express/qeth Device Driver: Improve invalid frame handlingPreviously, a single invalid frame in a receive buffer would trigger discarding the entire buffer. With this addition, we are able to sort out and process valid frames within receive buffers containing invalid ones
  • HiperSockets/qeth Device Driver: Support Multi-WriteSend multiple frames for the same target in one go. This reduces CPU utilization, speeds up the data transfer, and reduces receiver-side interrupts.
