So I just tried the patch you linked on the cover letter[1], and I am
still getting the build error described above:

arch/um/drivers/pcap_user.c:35:12: error: conflicting types for ‘pcap_open’
static int pcap_open(void *data)
^~~~~~~~~
In file included from /usr/include/pcap.h:43,
from arch/um/drivers/pcap_user.c:7:
/usr/include/pcap/pcap.h:859:18: note: previous declaration of ‘pcap_open’ was here
PCAP_API pcap_t *pcap_open(const char *source, int snaplen, int flags,

Looking at the patch, I wouldn't expect it to solve this problem.

Are there maybe different conflicting libpcap-dev libraries and I have
the wrong one? Or is this just still broken?
