tiens j'aurai pas deviné que c'étais controlable. Par contre, ethtool -i me dit que supports-eeprom-access:no

Comment monter un réseau 10Gbit/s chez soi
« Réponse #5149 le: Hier à 23:07:24 »
Pour les accès eeprom ou autres, il y a les ioctl rtltool du driver propriétaire, mais l'outil ne semble pas public.
Et à moins de reconnaitre les configs PCIe, on ne saurait pas quoi changer (et en cas d'erreur il faudrait reprogrammer l'eeprom manuellement).

Tu peux essayer les deux commandes :
Code: [Sélectionner]
# Set PCI_EXP_LNKCTL2 : PCI_EXP_LNKCTL2_TLS_16_0GT
setpci -v -s c0:00.0 CAP_EXP+0x30.w=0x0004:0x000f

# Set PCI_EXP_LNKCTL PCI_EXP_LNKCTL_RL (Retrain Link)
setpci -v -s c0:00.0 CAP_EXP+0x10.w=0x0020:0x0020

Si ça ne suffit pas, il faudrait tenter de changer LnkCap / LnkCap2 avant :
Code: [Sélectionner]
# Set PCI_EXP_LNKCAP :  PCI_EXP_LNKCAP_MLW=1
setpci -v -s c0:00.0 CAP_EXP+0x0C.w=0x0010:0x03f0

# Set PCI_EXP_LNKCAP :  PCI_EXP_LNKCAP_SLS_16_0GB
setpci -v -s c0:00.0 CAP_EXP+0x0C.w=0x0004:0x000f

# Set PCI_EXP_LNKCAP2 :  set PCI_EXP_LNKCAP2_SLS_16_0GB bit
setpci -v -s c0:00.0 CAP_EXP+0x2C.w=0x0010:0x0010

Pas d'amélioration avec les deux set de cmds + retrain à nouveau après la seconde.

La seule différence que je vois est "LnkCtl2 : Target Link Speed : 16GT/s" mais vu que les LnkCap ont pas changé (toujours 8GT/s) malgré les setpci - pas trop surpris que ca change rien.
