E.g.:
[myprofile]
process=myprocess1
process2=myprocess2.*
The myprofile will be recommended if there are 'myprocess1' and
'myprocess2.*' (e.g. myprocess2, myprocess21, myprocess2_whatever)
running.

Subject:
The realtime guest profile uses the RT kernel default priority
assignment for the ksoftird, rcuc, and ktimersoftd kernel threads,
which is:
17 FF 2 [rcuc/1] *
19 FF 1 [ktimersoftd/1] *
20 TS - [ksoftirqd/1] *
This doesn't allow running a PMD thread with fifo:1 in the
guest, since this will starve ktimersoftd and ksoftirqd if
those threads ever become runnable.
The solution is to use the same priority assigment we use
in the host where we've been running PMD threads with
fifo:1 priorities without problems. This assignment is:
151 FF 4 [rcuc/15] *
153 FF 3 [ktimersoftd/15] *
154 FF 2 [ksoftirqd/15] *
This patch just copies the [scheduler] section from the
host profile.

By default the timer tick will fire at the same time on all
CPUs. This causes the jiffies_lock to get contended in the
real-time kernel, as it's a raw spinlock. skew_tick=1 causes
the timer tick to fire at different times on all CPUs,
fixing the contention.
Note skew_tick=1 usage is going to be propagated to the
NFV profiles as well.

Plugin_net instances can now be given a new 'ring' option with
the following values (see ethtool(8) for their meaning):
rx N
rx-mini N
rx-jumbo N
tx N
The syntax is the same as the syntax for 'coalesce' and 'features'
parameters introduced in commit bc5d7acca8.
Example:
[net]
ring=rx 1024 tx 512
