Strict-aliasing rules are violated by cast to uint16_t* in flowgen.c
and the calculated IP checksum is wrong on GCC 9 and GCC 10.

Insert a compiler barrier to make sure that the IP checksum calculation
happens after setting all the fields of the IP header.

I don't think this is nece
d
uio_info.open, which only does pci_disable_device() and
pci_enable_device(),
but this prevent app receiving packets in its second run, independent
from app terminated gracefully or not. Any idea why this is not working?
btw, I can produce the problematic case, as George Prekas described in:
ht
here https://github.com/prekageo/allmemscan
$ make
$ sudo insmod allmem.ko
$ sudo ./allmemscan 28 prekageo_was_here
Optionally:
$ sudo dd if=/dev/allmem bs=4K skip=PAGE count=1 | hexdump -C | less
