* [xen] Provide 18 4kB receive buffers to work around xen-netback bugMichael Brown2017-05-191-6/+31
| | | | | | | | | | | | | | | The Xen network backend (xen-netback) suffered from a regression between upstream Linux kernels 3.18 and 4.2 inclusive, which would cause packet reception to fail unless at least 18 receive buffers were available. This bug was fixed in kernel commit 1d5d485 ("xen-netback: require fewer guest Rx slots when not using GSO"). Work around this bug in affected versions of xen-netback by providing the requisite 18 receive buffers.
