This patch introduce eir_skb_put_data() that can be used to simplify operations on eir in goal of eliminating the necessity of intermediary buffers. eir_skb_put_data() is in pair to what eir_append_data() does with help of eir_len, but without awkwardness when passing return value to skb_put() (as it returns updated offset not size).

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use "flexible array members" for these cases. The older style of one-element or zero-length arrays should no longer be used.

Since the starting value in the for loop is greater than or equal to 1, the restriction is CAS_FLAG_REG_PLUS is in the file cassini.h is defined as 0x1 by macro, and the for loop and if condition is not satisfied, so the code here is redundant.

Simon Horman says: ==================== Add AF_XDP zero-copy support for NFP Niklas Söderlund says: This series adds AF_XDP zero-copy support for the NFP driver. The series is based on previous work done by Jakub Kicinski. Patch 1/5 and 2/5 prepares the driver for AF_XDP support by refactoring functions that will act differently once AF_XDP is active or not making the driver easier to read and by preparing some functions to be reused outside the local file scope. Patch 3/5 and 4/5 prepares the driver for dealing the UMEM while finally patch 5/5 adds AF_XDP support. Based on work by Jakub Kicinski. ==================== Signed-off-by: -
Niklas Söderlund authored
This patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do so by adding a separate NAPI poll function that is attached to a each channel when the XSK socket is attached with XDP_SETUP_XSK_POOL, and restored when the XSK socket is terminated, this is done per channel. Support for XDP_TX is implemented and the XDP buffer can safely be moved from the Rx to the Tx queue and correctly freed and returned to the XSK pool once it's transmitted. Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS will allocate a new buffer and copy the zero-copy frame prior passing it to the kernel stack. This patch is based on previous work by Jakub Kicinski. Signed-off-by:

Following functions are processed: sch_handle_egress() __dev_xmit_skb() enqueue_to_backlog() do_xdp_generic() sch_handle_ingress() __netif_receive_skb_core() and following new drop reasons are added (what they mean can be see in the document of them): SKB_DROP_REASON_QDISC_EGRESS SKB_DROP_REASON_QDISC_DROP SKB_DROP_REASON_CPU_BACKLOG SKB_DROP_REASON_XDP SKB_DROP_REASON_QDISC_INGRESS SKB_DROP_REASON_PTYPE_ABSENT In order to add skb drop reasons to kfree_skb_list(), the function kfree_skb_list_reason() is introduced in the 2th patch, which will be used in __dev_xmit_skb() in the 3th patch. ==================== Signed-off-by:
