support MAC GMII mode,是主模式,PHY GMII mode是从模式, 他们是只能MAC GMII mode连接PHY GMII mode,PHY GMII mode直接不能直接连接, PHY和MAC是TCP/IP七层中中的术语。PHY指物理层(第一层)。MAC在Data Link层(第二层) 问:如何实现单片以太网微控制器? 答:诀窍是将微控制器、以太网媒体接入控制器(MAC...
int hci_le_setdefault_phy(uint8_t phy_mode, uint16_t all_phys); 参数解释: phy_mode:这个参数定义了要使用的物理层模式。可能的值包括 LE_PHY_1M, LE_PHY_2M, LE_PHY_Coded 等。 all_phys:这个参数是一个位掩码,用于指定哪些物理层应该被设置。例如,如果 all_phys 的值为 0x0003,那么物理层 1M...
PHY(物理层)以太网中涉及一般交换芯片可选择两种模式：MAX模式或PHY模式。PHY芯片没得选只能做为物理层芯片。当MAX芯片在PHY MODE下，亦只能做物理层芯片。
int phy_mode; /* Determine if the PHY adds a 2 ns TX delay or the MAC handles it */ phy_mode = device_get_phy_mode(ðqos->pdev->dev); if (phy_mode == PHY_INTERFACE_MODE_RGMII_ID || phy_mode == PHY_INTERFACE_MODE_RGMII_TXID) phase_shift = 0; else phase_shift = RGMII...
Additionally, due to user specific path losses and shadowing situations, a suitable PHY-Mode has to be chosen for each allocated subcarrier. An optimal combination of subcarrier allocation schemes and PHY-Mode selection procedures will be discussed in this paper. 展开 关键词: FDMA multi user ...

LoongArch: Fix GMAC's phy-mode definitions in dts Browse files The GMAC of Loongson chips cannot insert the correct 1.5-2ns delay. So we need the PHY to insert internal delays for both transmit and receive data lines from/to the PHY device. Fix this by changing the "phy-mode" from ...
