0000 0 Structure $NETWK Relocation mapping for virtual NIC
00000001 $NET_VER 1 Mapping version number for this
DSECT. Version is independent of
the CP level and need only be
changed when this DSECT is
changed. The convention is to
increment by 1.
0000 0 Signed 2 $NET_HDRL Header length (in bytes)
0002 2 Signed 2 $NET_BITL Length of mapped bits (in bytes)
0004 4 Signed 4 * Reserved for future use
00000008 $NET_HDLN *-$NETWK Length of header (bytes)
Bit map: Contains the NETWK flags that are subject to
relocation. These bits are defined sequentially,
regardless of how they are defined in HCPNETWK.
This yields a consistent mapping that ensures
compatibility when a guest is relocated between
systems at differing service levels.
Names in the comments column indicate the control
block byte which contains the flag. This name is
subject to change if the flag definition changes.
====> NEVER change bits which already exist here.
====> NEVER change the order of bits in this section.
====> ALWAYS add new bits at the end of this section,
together with new flag bytes as required.

Data: Contains all HCPNETWK data that is subject to
relocation, except for flag bits, which are
handled separately.
All fields are defined as XLnn to avoid alignment
warnings and to pack the data efficiently.
