Modify the ethernet driver to use TX complete interrupts. Adds HAL ethernet TX complete callback and locking semaphore. Due to changing behavior/content of the TX DMA descriptors on STM32H7 series, based on the state of the IP, it is more reliable to wait for the TX complete interrupt to check for DMA end of transmission event. This avoids polling the DMA_DESC_OWN bit in the descriptors. Improves reliability and performance of the ethernet peripheral. Tested on CoapServer sample, Dumb HTTP server, telnet sample.
