From a9e34753118e1fea1cb5d7dc7ad09b8b66fa926f Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Tue, 12 Oct 2021 16:25:20 +0300 Subject: [PATCH 15/26] sff-8079: Split SFF-8079 parsing function SFF-8079, unlike CMIS and SFF-8636, only has a single page and therefore its parsing function (i.e., sff8079_show_all()) is called from both the IOCTL and netlink paths with a buffer pointing to that single page. In future patches, the netlink code (i.e., netlink/module-eeprom.c) will no longer call the SFF-8079 code with a buffer pointing to the first 128 bytes of the EEPROM. Instead, the SFF-8079 code will need to request the needed EEPROM data, as will be done in CMIS and SFF-8636. Therefore, as a preparation for this change, split the main parsing function into IOCTL and netlink variants. No functional changes intended. commit: 9fdf45c Reference: https://git.kernel.org/pub/scm/network/ethtool/ethtool.git/commit/?id=9fdf45ca1726 Signed-off-by: Ido Schimmel --- ethtool.c | 4 ++-- internal.h | 3 ++- netlink/module-eeprom.c | 2 +- sfpid.c | 12 +++++++++++- 4 files changed, 16 insertions(+), 5 deletions(-) diff --git a/ethtool.c b/ethtool.c index fa5a347..461d1f2 100644 --- a/ethtool.c +++ b/ethtool.c @@ -4901,10 +4901,10 @@ static int do_getmodule(struct cmd_context *ctx) switch (modinfo.type) { #ifdef ETHTOOL_ENABLE_PRETTY_DUMP case ETH_MODULE_SFF_8079: - sff8079_show_all(eeprom->data); + sff8079_show_all_ioctl(eeprom->data); break; case ETH_MODULE_SFF_8472: - sff8079_show_all(eeprom->data); + sff8079_show_all_ioctl(eeprom->data); sff8472_show_all(eeprom->data); break; case ETH_MODULE_SFF_8436: diff --git a/internal.h b/internal.h index ed4f180..aa033ca 100644 --- a/internal.h +++ b/internal.h @@ -387,7 +387,8 @@ int rxclass_rule_ins(struct cmd_context *ctx, int rxclass_rule_del(struct cmd_context *ctx, __u32 loc); /* Module EEPROM parsing code */ -void sff8079_show_all(const __u8 *id); +void sff8079_show_all_ioctl(const __u8 *id); +void sff8079_show_all_nl(const __u8 *id); /* Optics diagnostics */ void sff8472_show_all(const __u8 *id); diff --git a/netlink/module-eeprom.c b/netlink/module-eeprom.c index 18b1abb..101d594 100644 --- a/netlink/module-eeprom.c +++ b/netlink/module-eeprom.c @@ -323,7 +323,7 @@ static void decoder_print(void) switch (module_id) { case SFF8024_ID_SFP: - sff8079_show_all(page_zero->data); + sff8079_show_all_nl(page_zero->data); break; case SFF8024_ID_QSFP: case SFF8024_ID_QSFP28: diff --git a/sfpid.c b/sfpid.c index da2b3f4..c214820 100644 --- a/sfpid.c +++ b/sfpid.c @@ -396,7 +396,7 @@ static void sff8079_show_options(const __u8 *id) printf("%s Power level 3 requirement\n", pfx); } -void sff8079_show_all(const __u8 *id) +static void sff8079_show_all_common(const __u8 *id) { sff8079_show_identifier(id); if (((id[0] == 0x02) || (id[0] == 0x03)) && (id[1] == 0x04)) { @@ -439,3 +439,13 @@ void sff8079_show_all(const __u8 *id) sff8079_show_ascii(id, 84, 91, "Date code"); } } + +void sff8079_show_all_ioctl(const __u8 *id) +{ + sff8079_show_all_common(id); +} + +void sff8079_show_all_nl(const __u8 *id) +{ + sff8079_show_all_common(id); +} -- 2.30.0
