Willem de Bruijn 4633c9e07b net-packet: fix null pointer exception in rollover mode ... Rollover can be enabled as flag or mode. Allocate state in both cases. This solves a NULL pointer exception in fanout_demux_rollover on referencing po->rollover if using mode rollover. Also make sure that in rollover mode each silo is tried (contrary to rollover flag, where the main socket is excluded after an initial try_self). Tested: Passes tools/testing/net/psock_fanout.c, which tests both modes and flag. My previous tests were limited to bench_rollover, which only stresses the flag. The test now completes safely. it still gives an error for mode rollover, because it does not expect the new headroom (ROOM_NORMAL) requirement. I will send a separate patch to the test.
