+Subject: net: sfp: rework the RollBall PHY waiting code
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+RollBall SFP modules allow the access to PHY registers only after a
+certain time has passed. Until then, the registers read 0xffff.
+
+Currently we have quirks for modules where we need to wait either 25
+seconds or 4 seconds, but recently I got hands on another module where
+the wait is even shorter.
+
+Instead of hardcoding different wait times, lets rework the code:
+- increase the PHY retry count to 25
+- when RollBall module is detected, increase the PHY retry time from
+ 50ms to 1s

+
+Commit 2f3ce7a56c6e ("net: sfp: rework the RollBall PHY waiting code")
+changed the long wait before accessing RollBall / FS modules into
+probing for PHY every 1 second, and trying 25 times.
+
+Wei Lei reports that this does not work correctly on FS modules: when
+initializing, they may report values different from 0xffff in PHY ID
+registers for some MMDs, causing get_phy_c45_ids() to find some bogus
+MMD.
+
+Fix this by adding the module_t_wait member back, and setting it to 4
+seconds for FS modules.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Enhance the quirk for Fibrestore 2.5G copper SFP module. The original
+commit e27aca3760c0 ("net: sfp: add quirk for FS's 2.5G copper SFP")
+introducing the quirk says that the PHY is inaccessible, but that is
+not true.
+
+The module uses Rollball protocol to talk to the PHY, and needs a 4
+second wait before probing it, same as FS 10G module.
+
+The PHY inside the module is Realtek RTL8221B-VB-CG PHY. The realtek
+driver recently gained support to set it up via clause 45 accesses.
