; ZeroTier One Virtual Network Port NDIS6 Driver
;
; Modified by ZeroTier, Inc. - https://www.zerotier.com/
;
; (1) Comment out 'tun' functionality and related features such as DHCP
; emulation, since we don't use any of that. Just want straight 'tap'.
; (2) Added custom IOCTL to enumerate L2 multicast memberships.
; (3) Increase maximum number of multicast memberships to 128.
; (4) Set default and max device MTU to 2800.
; (5) Rename/rebrand driver as ZeroTier network port driver.
;
; Original copyright below. Modifications released under GPLv2 as well.
