When fixing for shift/reduce conflicts, possibility to invert the last
expression by prefixing with '!' or 'not' was accidentally removed.
Fix this by allowing for expr to be an inverted expr so that any
reference to it in exprlist accepts the inverted prefix.

commit c7c1a1ef51 ("bridge: colorize output and use JSON print library")
broke previous use of -c to represent compressvlans. This restores
previous use of -c to represent compressvlans. Understand the original
motivation to use -c to represent color consistently everywhere but
there are apps and network interface managers out there that are already
using -c to prepresent compressed vlans.

Kernel commit 48872c11b772 ("net_sched: sch_fq: add dctcp-like marking")
added support for TCA_FQ_CE_THRESHOLD attribute.
This patch adds iproute2 support for it.
It also makes sure fq_print_xstats() can deal with smaller tc_fq_qd_stats
structures given by older kernels.
Usage :
FQATTRS="ce_threshold 4ms"
TXQS=8
for ETH in eth0
do
tc qd del dev $ETH root 2>/dev/null
tc qd add dev $ETH root handle 1: mq
for i in `seq 1 $TXQS`
do
tc qd add dev $ETH parent 1:$i fq $FQATTRS
done
done

The comment about providing a proper message seems similar to
the comment in the kernel which says:
/* hack -- fix at some point with proper message
This is how we indicate to tc that there is no VQ
at this DP */
it's unclear what that message would be, and whether it's needed.

In order to compare BPF map symbol type correctly in regard to the
latest LLVM, commit 7a04dd84a7 ("bpf: check map symbol type properly
with newer llvm compiler") compares map symbol type to both NOTYPE and
OBJECT. To do so, it first retrieves the type from "sym.st_info" and
stores it into a temporary variable.
However, the type is collected from the symbol "sym" before this latter
symbol is actually updated. gelf_getsym() is called after that and
updates "sym", and when comparison with OBJECT or NOTYPE happens it is
done on the type of the symbol collected in the previous passage of the
loop (or on an uninitialised symbol on the first passage). This may
eventually break map collection from the ELF file.
Fix this by assigning the type to the temporary variable only after the
call to gelf_getsym().

Also, a valid value is a positive value. To let the kernel chooses a value,
