Hmmm...

$ grep MaxTxPacketSize drivers/net/r8169.c
	MaxTxPacketSize	= 0xec,	/* 8101/8168. Unit of 128 bytes. */
	RTL_W8(MaxTxPacketSize, TxPacketMax);
	RTL_W8(MaxTxPacketSize, TxPacketMax);
	RTL_W8(MaxTxPacketSize, TxPacketMax);
	RTL_W8(MaxTxPacketSize, TxPacketMax);
	RTL_W8(MaxTxPacketSize, TxPacketMax);
	RTL_W8(MaxTxPacketSize, TxPacketMax);
	RTL_W8(MaxTxPacketSize, 0x27);
	RTL_W8(MaxTxPacketSize, TxPacketMax);
	RTL_W8(MaxTxPacketSize, TxPacketMax);

Is the 0x27 value still in units of 128 bytes ?

Could it be TxPacketMax as everywhere else in the driver instead of 0x27 ?
