net: phylink: fix sphinx complaint about invalid literal

2023-09-06T06:46:49+00:00

sphinx complains about the use of "%PHYLINK_PCS_NEG_*": Documentation/networking/kapi:144: ./include/linux/phylink.h:601: WARNING: Inline literal start-string without end-string. Documentation/networking/kapi:144: ./include/linux/phylink.h:633: WARNING: Inline literal start-string without end-string. These are not valid symbols so drop the '%' prefix. Alternatively we could use %PHYLINK_PCS_NEG_\* (escape the *) or use normal literal ``PHYLINK_PCS_NEG_*`` but there is already a handful of un-adorned DEFINE_* in this file.

net: phylink: remove legacy mac_an_restart() method

2023-07-18T07:47:09+00:00

The mac_an_restart() method is now completely unused, and has been superseded by phylink_pcs support. Remove this method. Since phylink_pcs_mac_an_restart() now only deals with the PCS, rename the function to remove the _mac infix.

phylink: ReST-ify the phylink_pcs_neg_mode() kdoc

2023-06-27T16:33:54+00:00

Stephen reports warnings when rendering phylink kdocs as HTML: include/linux/phylink.h:110: ERROR: Unexpected indentation. include/linux/phylink.h:111: WARNING: Block quote ends without a blank line; unexpected unindent. include/linux/phylink.h:614: WARNING: Inline literal start-string without end-string. include/linux/phylink.h:644: WARNING: Inline literal start-string without end-string. Make phylink_pcs_neg_mode() use a proper list format to fix the first two warnings. The last two warnings, AFAICT, come from the use of shorthand like phylink_mode_*(). Perhaps those should be special-cased at the Sphinx level.

net: phylink: pass neg_mode into phylink_mii_c22_pcs_config()

2023-06-23T02:41:01+00:00

Convert fman_dtsec, xilinx_axienet and pcs-lynx to pass the neg_mode into phylink_mii_c22_pcs_config(). Where appropriate, drivers are updated to have neg_mode passed into their pcs_config() and pcs_link_up() functions. For other drivers, we just hoist the call to phylink_pcs_neg_mode() to their pcs_config() method out of phylink_mii_c22_pcs_config().

net: phylink: add PCS negotiation mode

2023-06-23T02:41:01+00:00

PCS have to work out whether they should enable PCS negotiation by looking at the "mode" and "interface" arguments, and the Autoneg bit in the advertising mask. This leads to some complex logic, so lets pull that out into phylink and instead pass a "neg_mode" argument to the PCS configuration and link up methods, instead of the "mode" argument. In order to transition drivers, add a "neg_mode" flag to the phylink PCS structure to PCS can indicate whether they want to be passed the neg_mode or the old mode argument.
