[PATCH 3/4] Removing the udp_reader efi_binding
This extra socket cause the EFI udp stack to duplicate every packet
to be able to provide them to both udp_reader and socket->net.efi.binding.
The ones in socket->net.efi.binding were never read so they accumulated in
the stack on EFI side making the stack slower and slower.
Slow enough to not be able to download a kernel+initramfs before the EFI
timeout (5 minutes).

[PATCH 2/5] ntfs: remove unused variable and have ntfssect use char API calls
The variable 'ok' is never used and generates a warning. Remove it. Also
ntfssect.c is designed to be compiled in non Unicode mode when using
MSVC compilers, so remove all ambiguity about it (LPCTSTR -> LPCSTR, use
of 'A' API calls) so that it doesn't break when compiled in Unicode
mode, which is what Rufus uses with MSVC.

UEFI syslinux PXE boot issues
...this a few years back:
There are other issues with PXE over UEFI with syslinux. I got it to
work by using version 6.04_pre1 plus 3 pathes and building from source:
efi-udp-core_udp_connect-use-SubnetMask-not-StationA.patch
efi-udp-Add-retry-disabling-UseDefaultAddress.patch
efi-udp-Removing-the-udp_reader-efi_binding.patch
Patches are cherry-picked commits from syslinux git tree.
Fixes the decaying TFTP transfer rate problem.

syslinux.efi pxeboot across multiple subnets
I did change both instances of txdata->GatewayAddress, but I think
something may be wrong in my toolchain. If I extract syslinux.zip and
attempt to make from there (without modifying any files), the cached DHCP
packet isn't read on the same subnet.
I receive "Succeed to download NBP file." twice before anything from
syslinux is loaded, so I believe the duplicate request for
