The patch contains following changes: * In conditional checks, always check for NULL or 0 instead of negating values * Use malloc and free explicitely, instead of ENA_MEM_FREE and ENA_MEM_FREE (the dmadev passed to macro is never used, and could be a little misleading) * Always check for NULL after calling malloc (few checks were missing) * Rework naming of the goto tags in ena_attach() for consistency * Fix error handling in ena_attach() - few goto instructions were leading to the wrong tag * Destroy MMIO req read request if attach failed * Remove checking for NULL after calling malloc with M_WAITOK flag Submitted by: Michal Krawczyk <mk@semihalf.com> Reviewed by: byenduri_gmail.com Obtained from: Semihalf Sponsored by: Amazon.com, Inc.

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
NOTES contains entries and documentation for all possible
