net: ena: Update LLQ header length in ena documentation
LLQ entry length is 128 bytes. Therefore the maximum header in the entry is calculated by: tx_max_header_size = LLQ_ENTRY_SIZE - DESCRIPTORS_NUM_BEFORE_HEADER * 16 = 128 - 2 * 16 = 96 This patch updates the documentation so that it states the correct max header length.

- **Low Latency Queue (LLQ) mode or "push-mode":**

In this mode the driver pushes the transmit descriptors and the

first 128 bytes of the packet directly to the ENA device memory

first 96 bytes of the packet directly to the ENA device memory

device. For this operation mode, the driver uses a dedicated PCI

device memory BAR, which is mapped with write-combine capability.
