David Cermak	7af358ed93	esp_eth: Fix w5500 to break from potentially infinite tx loop ... The issue typically happens for link-down during Tx. Added two retry levels, one before checking the sanity of the w5500 phy register and another for the Tx done itself (if the device is in the sane state) Closes https://github.com/espressif/esp-idf/issues/6233	2021-04-12 07:59:40 +00:00
David Cermak	dfe9580967	esp_eth: Fix w5500 to correctly read registers on -Os ... Reading SPI data may come in 4-byte units and thus result in unwanted overwrites if smaller size registers read, especially if multiple placed one after another. Fixed by using direct reads to `trans` structure for sizes smaller or equal to 4. Closes https://github.com/espressif/esp-idf/issues/6579	2021-04-12 07:59:40 +00:00
morris	1e905acacf	eth: support W5500 MAC RAW mode ... W5500 features an Ethernet MAC+PHY, plus a HW SOCKET implementation. But in IDF, we only use software TCP/IP stack, which means we have to bypass the HW TCP/IP stack in W5500. So we enables the MAC RAW mode in W5500.	2020-11-16 13:30:49 +08:00
