Hans Petter Selasky a9b66dbd91 Allow the tcp_lro_flush_all() function to be called when the control
structure is zeroed, by setting the VNET after checking the mbuf count
for zero. It appears there are some cases with early interrupts on some
network devices which still trigger page-faults on accessing a NULL "ifp"
pointer before the TCP LRO control structure has been initialized.
This basically preserves the old behaviour, prior to
9ca874cf74 .

No functional change.

FreeBSD Source:

This is the top level of the FreeBSD source directory.

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.

For copyright information, please see the file COPYRIGHT in this directory. Additional copyright information also exists for some sources in this tree - please see the specific source directories for more information.

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7), config(8), FreeBSD handbook on building userland, and Handbook for kernels for more information, including setting make(1) variables.
