The code added in 976dca372 uses h2be64, defined in endian.h.
While this is pulled in around some corners for glibc (see
below), that's not the case for musl and an explicit include
is required.

This time also to the netdev list, sorry...

The commit message needs to be reworded.
Should use fixes tag than a specific commit hash value.

The code added in "f_flower: implement pfcp opts" uses h2be64,
defined in endian.h. While this is pulled in around some corners
for glibc (see below), that's not the case for musl and an
explicit include is required there.

Other parts of flower code use htonll().
It would have been better to be consistent and not use h2be64() at all.

htonl is used for 32-bit numbers. It won't work properly with 64-bit numbers.

Sorry, I missed the second "l".
