4. Thomas, Mellanox: Would be good to have a public overview of Windows 
Development progress.
    Possibly public editable page + public info page.
    AR: Thomas/Harini : to seek to create page on dpdk.org

5. Haseeb, Marvell: In the process of supporting Marvell FastlinQ cards 
on the 18.08 draft branch.
    The changes are done in netuio, pci and qede modules.
    We’re completing internal review and will be able to send the 
changes for review soon.

7. Ranjit/Pallavi, Intel: We may need to abstract out some common code, 
if it’s not supported on windows.
    dirent.h      - priority to find license info for this file
    getopt.h      - priority to find license info for this file
    pthread.h -> contains implementation
    rand48.h
    sched.h -> contains implementation
    syslog.h        - priority to find license info for this file
    termios.h
    unistd.h -> contains implementation
    net/ethernet.h
    netinet/in.h -> contains implementation
    netinet/tcp.h -> contains only include guard
    sys/netbsd/queue.h -> contains implementation
    sys/_iovec
    sys/_sockaddr
    sys/_storage.h
    sys/_termios.h
    sys/_types.h
    sys/cdefs.h -> contains only include guard
    sys/mman.h
    sys/queue.h

8. Ranjit/Pallavi/Zhaoyan, Intel: Meson/make - Windows is now integrated 
into Intel CI and reporting to dpdk.org patchwork.
    Request made to remove GCC line & update Kernel version capture info 
for the test listing against windows.

9. Harini, Microsoft: MS Patches in preparation of Windows support for 
CXGBE is already available in 19.05 repo upstream.
    CXGBE PMD will compile fine against Windows DPDK using Intel C++ 
Compiler up to v19.02.
[PATCH 0/4] net/cxgbe: fix build for Microsoft Windows OS support (Rahul 
Lakkireddy)
[PATCH 1/4] net/cxgbe: use relative paths for including header files 
(Rahul Lakkireddy) [PATCH 2/4] net/cxgbe: fix macros related to logs for 
Windows (Rahul Lakkireddy)
[PATCH 3/4] net/cxgbe: only redefine symbols when not available for 
Windows (Rahul Lakkireddy)

9. Ravi, Cisco: Ravi Anand team working with the PMD for the Cisco 
Virtual interface Cards.

10. Tal, Mellanox: For bus/pci: Can refer to windpdk-v18.08 branch in 
draft repo.
    Code there is built using clang and functional. (No meson support yet).
    Currently working on Ninja & meson compiler. But hit some issues and 
resolved by upgrading (able to debug: upgrade CLang to version 8.0.0) & 
recompiling.
    Now able to build in debug mode (DPDK.org guidance needs to be 
updated). For new patches from 19.08 onwards: use repo windpdk-next-dev 
(Harini is the maintainer).
    Windows will only use meson, going forward. Currently compiling with 
clang, but not with meson.

11. Ranjit, Intel: common source using a function asprintf().
    Does allocation of buffers. This function does not exist for windows.
    How should this be resolved? We should change the common code to 
enable this for windows.
    (Thomas) Please check with the author of the change, David Marchand.
