Author: adrian Date: Mon Feb 6 03:06:11 2017 New Revision: 313311 URL: https://svnweb.freebsd.org/changeset/base/313311 Log: [iwm] Sync nvm parsing code with Linux iwlwifi. * sc->sc_nvm becomes sc->nvm_data and is now a pointer instead of an inlined struct. * Add sc->eeprom_size and sc->nvm_hw_section_num configuration values to struct iwm_softc. * For now continue to avoid negative error return-values, and use pointer variables for some return values, as before. * Continue to omit LAR (location aware regulatory) related code as well. Tested: * Intel 7260, STA mode (2GHz) Obtained from: dragonflybsd commit 39f8331b1a6f295291e08c377da12a8e7a5436c0 Modified: head/sys/dev/iwm/if_iwm.c head/sys/dev/iwm/if_iwm_scan.c head/sys/dev/iwm/if_iwm_util.c head/sys/dev/iwm/if_iwmreg.h head/sys/dev/iwm/if_iwmvar.h Modified: head/sys/dev/iwm/if_iwm.c ============================================================================== --- head/sys/dev/iwm/if_iwm.c Mon Feb 6 02:20:05 2017 (r313310) +++ head/sys/dev/iwm/if_iwm.c Mon Feb 6 03:06:11 2017 (r313311) @@ -260,20 +260,23 @@ static int iwm_post_alive(struct iwm_sof static int iwm_nvm_read_chunk(struct iwm_softc *, uint16_t, uint16_t, uint16_t, uint8_t *, uint16_t *);
