When napi_gro_receive\nis used, the driver must either call napi_complete/napi_rx_complete, or\ncall napi_gro_flush in softirq context if the driver uses the primitives\n__napi_complete/__napi_rx_complete.\n\nProtocols will set the gro_receive and gro_complete function pointers in\norder to participate in this scheme.\n\nIn addition to the packet, gro_receive will get a list of currently held\npackets. Each packet in the list has a same_flow field which is non-zero\nif it is a potential match for the new packet. For each packet that may\nmatch, they also have a flush field which is non-zero if the held packet\nmust not be merged with the new packet.\n\nOnce gro_receive has determined that the new skb matches a held packet,\nthe held packet may be processed immediately if the new skb cannot be\nmerged with it. In this case gro_receive should return the pointer to\nthe existing skb in gro_list. Otherwise the new skb should be merged into\nthe existing packet and NULL should be returned, unless the new skb makes\nit impossible for any further merges to be made (e.g., FIN packet) where\nthe merged skb should be returned.\n\nWhenever the skb is merged into an existing entry, the gro_receive\nfunction should set NAPI_GRO_CB(skb)-\u003esame_flow. Note that if an skb\nmerely matches an existing entry but can\u0027t be merged with it, then\nthis shouldn\u0027t be set.\n\nIf gro_receive finds it pointless to hold the new skb for future merging,\nit should set NAPI_GRO_CB(skb)-\u003eflush.\n\nHeld packets will be flushed by napi_gro_flush which is called by\nnapi_complete and napi_rx_complete.\n\nCurrently held packets are stored in a singly liked list just like LRO.\nThe list is limited to a maximum of 8 entries. In future, this may be\nexpanded to use a hash table to allow more flows to be held for merging.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: David S.

Documentation is also updated\naccordingly.\n\nIssues and brief design overview:\n\n(1) Kernel-initiated creation / destruction of kernel objects is not\n possible with configfs -- the lifetimes of the \"config items\" is managed\n exclusively from userspace. But netconsole must support boot/module\n params too, and these are parsed in kernel and hence netpolls must be\n setup from the kernel. Joel Becker suggested to separately manage the\n lifetimes of the two kinds of netconsole_target objects -- those created\n via configfs mkdir(2) from userspace and those specified from the\n boot/module option string. This adds complexity and some redundancy here\n and also means that boot/module param-created targets are not exposed\n through the configfs namespace (and hence cannot be updated / destroyed\n dynamically). However, this saves us from locking / refcounting\n complexities that would need to be introduced in configfs to support\n kernel-initiated item creation / destroy there.\n\n(2) In configfs, item creation takes place in the call chain of the\n mkdir(2) syscall in the driver subsystem. If we used an ioctl(2) to\n create / destroy objects from userspace, the special userspace program is\n able to fill out the structure to be passed into the ioctl and hence\n specify attributes such as local interface that are required at the time\n we set up the netpoll. For configfs, this information is not available at\n the time of mkdir(2). So, we keep all newly-created targets (via\n configfs) disabled by default. The user is expected to set various\n attributes appropriately (including the local network interface if\n required) and then write(2) \"1\" to the \"enabled\" attribute. Thus,\n netpoll_setup() is then called on the set parameters in the context of\n _this_ write(2) on the \"enabled\" attribute itself. This design enables\n the user to reconfigure existing netconsole targets at runtime to be\n attached to newly-come-up interfaces that may not have existed when\n netconsole was loaded or when the targets were actually created. All this\n effectively enables us to get rid of custom ioctls.\n\n(3) Ultra-paranoid configfs attribute show() and store() operations, with\n sanity and input range checking, using only safe string primitives, and\n compliant with the recommendations in Documentation/filesystems/sysfs.txt.\n\n(4) A new function netpoll_print_options() is created in the netpoll API,\n that just prints out the configured parameters for a netpoll structure.\n netpoll_parse_options() is modified to use that and it is also exported to\n be used from netconsole.\n\nSigned-off-by: Satyam Sharma \u003csatyam@infradead.org\u003e\nAcked-by: Keiichi Kii \u003ck-keiichi@bx.jp.nec.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: David S.

Only one of these clients may register an rx_hook,\nhowever. In practice, this restriction has not been problematic. It is\nworth mentioning, though, that the current design can be easily extended to\nallow for the registration of multiple rx_hooks.\n\nThe basic idea of the patch is that the rx_np pointer in the netpoll_info\nstructure points to the struct netpoll that has rx_hook filled in. Aside\nfrom this one case, there is no need for a pointer from the struct\nnet_device to an individual struct netpoll.\n\nA lock is introduced to protect the setting and clearing of the np_rx\npointer. The pointer will only be cleared upon netpoll client module\nremoval, and the lock should be uncontested.\n\nSigned-off-by: Jeff Moyer \u003cjmoyer@redhat.com\u003e\nSigned-off-by: David S.
