[lng-odp] [PATCH API-NEXT v1 12/19] linux-gen: packet: re-implement packet segmentation

From: Petri Savolainen Removed limitation to fixed number of segments (CONFIG_PACKET_MAX_SEGS) per packet. Packet headers carrying segment tables are now linked together with 'next_seg' pointer. Last header containing a segment table is pointed by 'last_seg' pointer.

[lng-odp] [PATCH API-NEXT v1 14/19] linux-gen: packet: implement static references

From: Petri Savolainen Implemented static references with a reference counter. Counter is zero when not used (reference API not used). Signed-off-by: Petri Savolainen Reviewed-by: Bill Fischofer

[lng-odp] [PATCH API-NEXT v1 16/19] linux-gen: packet: compress packet offset table

From: Petri Savolainen Use uint16_t (instead of size_t) for offsets and thus decrease size of the offset table into one fourth. Signed-off-by: Petri Savolainen Reviewed-by: Bill Fischofer Signed-off-by: Maxim

[lng-odp] [PATCH API-NEXT v1 17/19] linux-gen: packet: implement dynamic references

From: Petri Savolainen Use link headers to implement dynamic references. These are segment headers which first segment (seg[0]) does not point to itself but to a referenced segment. Link headers enable long chains of references (new dynamic references from previous

[lng-odp] [PATCH API-NEXT v1 18/19] linux-gen: packet: optimize header layout

From: Petri Savolainen Pack most often used data into the first and the last cache line of buffer header, and the first cache line of packet header. Reduce offsets and head-/tailroom fields to 16 bits, since those are in maximum as large as a segment, usually much

[lng-odp] [PATCH API-NEXT v1 19/19] linux-gen: move packet_to_buffer to packet_inlines.h

From: Maxim Uvarov odp_crypto.c is also uses packet_to_buffer() so move this function to common place. Signed-off-by: Maxim Uvarov --- /** Email created from pull request 179 (muvarov:api-next) ** https://github.com/Linaro/odp/pull/179 **
