Fix the relevant condition in netmap_mem_drop(): release the memory when the last user of netmap_adapter is gone, rather then when the last user of netmap_mem_d is gone.

This was causing spurious buffer frees when alternating between apps that used external buffers and apps that did not use them. - check na validitity under lock on detach - netmap_mem: fix leak on error path - nm_dispatch: fix compilation on Raspberry Pi MFC after: 2 weeks 2021-04-02T10:45:47Z Vincenzo Maffione vmaffione@FreeBSD.org 2021-04-02T10:43:19Z urn:sha1:9bad2638cc1882b44adb29a1cb1234f79e5c29f1 The fix in a56e6334d1b7ed6e6faaa8b4612d948005ba74f5 was accidentally reverted by commit 45c67e8f6b56b9744f01142747fadf291fe3fad2. 2021-04-02T07:01:20Z Vincenzo Maffione vmaffione@FreeBSD.org 2021-04-02T07:01:20Z urn:sha1:45c67e8f6b56b9744f01142747fadf291fe3fad2 No functional changes intended. 2021-03-29T16:29:01Z Vincenzo Maffione vmaffione@FreeBSD.org 2021-03-29T16:22:48Z urn:sha1:a6d768d845c173823785c71bb18b40074e7a8998 This feature enables applications to ask netmap to transmit or receive packets starting at a user-specified offset from the beginning of the netmap buffer. This is meant to ease those packet manipulation operations such as pushing or popping packet headers, that may be useful to implement software switches, routers and other packet processors. To use the feature, drivers (e.g., iflib, vtnet, etc.) must have explicit support. This change does not add support for any driver, but introduces the necessary kernel changes. However, offsets support is already included for VALE ports and pipes. 2020-10-03T09:33:29Z Vincenzo Maffione vmaffione@FreeBSD.org 2020-10-03T09:33:29Z urn:sha1:adf41f0788ffb9094e35fce67891765ef04b4849 Submitted by: milosz.kaniewski@gmail.com MFC after: 3 days 2020-09-01T21:19:14Z Mateusz Guzik mjg@FreeBSD.org 2020-09-01T21:19:14Z urn:sha1:662c13053f4bf2d6245ba7e2b66c10d1cd5c1fb9 2019-11-19T21:29:49Z Vincenzo Maffione vmaffione@FreeBSD.org 2019-11-19T21:29:49Z urn:sha1:a56e6334d1b7ed6e6faaa8b4612d948005ba74f5 Submitted by: neel@neelc.org Reviewed by: vmaffione MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D22390
