Hi Ian,

There is a problem in d1b08284ade "macvtap: convert to SKB paged frag
API."  It removes the initialization of "f" in zerocopy_sg_from_iovec()
which breaks it and causes a compile warning:
drivers/net/macvtap.c:509:5: warning: =E2=80=98f=E2=80=99 may be used u=
ninitialized
	in this function [-Wuninitialized]

regards,
dan carpenter
