[ovs-dev] [PATCH] dpif-linux: Don't reset kernel upcall_pids unintentionally.

2011-10-07 Thread Ben Pfaff
Commit b063d9f0 "datapath: Use unicast Netlink sockets for upcalls" that introduced an 'upcall_pid' member into struct dpif_linux_vport, struct dpif_linux_dp, and struct dpif_linux_flow neglected to do so only if the member was nonzero. This caused every datapath, vport, and flow operation to supp

[ovs-dev] [PATCH 1/2] datapath: Refactor actions in terms of match fields.

2011-10-07 Thread Pravin B Shelar
Almost all current actions can be expressed in the form of push/pop/set , where field is one of the match fields. We can create three base actions and take a field. This has both a nice symmetry and avoids inconsistencies where we can match on the vlan TPID but not set it. Following patch converts
